How Equilibrium Affects The Rate Of Reaction Ratio

The Vitamin C turned to a red/orange color with no physical/chemical reaction. For the salt the solution turned to an orange color with no physical/chemical reaction. With the Alka-Seltzer, the solution turned to a brown color with no reaction as well. Last but not least, the Baking soda turned to an orange/brown color with no reaction.

A chemical reaction is a process in which one or more substances, the reactants, are converted to one or more different substances, the products. (Britannica). It is through this redistribution of atoms that chemical reactions occur in many aspects of life on earth. These reactions occur both in the geology of the earth and in the burning of fuels.

The solution changed colour because, we added a reactant which means the forward reaction will occur faster than the reverse, which means there will be more products formed than reactants, because the reverse reaction is slower. The tube would feel slightly colder, because the reaction consumes the heat, and moves in the endothermic direction.

In the opposite case in which the concentration of A is decreased, according to Le Châtelier, the position of equilibrium will move so that the concentration of A increases again. More C and D will react to replace the A that has been removed. The position of equilibrium moves to the left.

The second unknown substance is bromide because both of them had the same reaction of turning darker yellow.

This specific reaction involves two colourless solutions that mix together after a certain amount of time it yields a blue colour change.

The hypothesis of this experiment was that an increase in concentration will increase the rate of reaction by decreasing the time taken for the colour change to occur. Figure 1.1 shows time on the x axis and concentration on the y axis, it can be seen that as [reactant] decreases, time increases.Thus, the results correlate with the hypothesis that an increase in concentration will produce a faster reaction time and subsequently a larger reaction rate - regardless of change in [KIO3] or [Na2S2O5], both reactants produce the same result.

A reaction is at equilibrium when the rates of the forward and the reverse reactions are equal (Ladon). Reactants react to form products and

Introduction: In this experiment we will be investigating how changing the temperature of the made up solution (copper chloride dihydrate and water) will impact the rate of a reaction when aluminium foil is dropped into it. We will determine this by selecting five different temperatures: 26 degrees, 36 degrees, 46 degrees, 56 degrees and 66 degrees and seeing at which temperature the reaction between the solution and aluminium foil produces the most heat. We will be recording the before and after temperatures after 2 minutes when the aluminium foil has been placed in the solution and also the average of the temperatures, this will help us determine if a hotter or colder

There are five main factors that affect that rate of a chemical reaction. These are the surface area of a solid reactant, the concentration and pressure of a reactant, temperature, the presence or absence of a catalyst and agitation. There is also another factor which is able to affect the rate which is the nature of the reactants.

The rate of reaction is defined as how fast the reactant is converted to the product and it is measured in moldm-3s-1

consumed. They have the ability to increase the rate of reaction in a chemical reaction. Catalysts achieve this by lowering the amount of energy required for a reaction to take place, which means that it occurs at a quicker rate. Potentially, molecules that would once have taken years to interact, can take seconds with the addition of a catalyst. The overall purpose of a catalyst is to ensure that reactions proceed effectively which is why a range of catalysts are commonly used in many elements of society. Common examples of where catalysts are used include; plastics, clean energy, converting energy sources to fuels, digestion and pharmaceuticals (Hamers, 2017).

Whenever HCl is added to the solution, the HCl will dissociate into ions, thus increasing the supply of H+ that would cause a shift in the equilibrium. Similarly, this is what also occurs when NaOH is added to the solution, the NaOH would dissociate and the OH would then neutralize the H+ thus forming an excess of H2O present in the solution that would ultimately lead to a shift in the equilibrium.

A clock reaction generally involves a mixture of solutions that, after a certain amount of time, displays a sudden colour change. This process demonstrates chemical kinetics in action, which is the study of chemical processes and rates of reaction where the reaction rate is the speed at which the chemical reaction proceeds. It is dependent on several factors that rely on one basic underlying principle called collision theory. In order for a reaction to occur, the reactant molecules must collide with each other with a certain minimum energy called the activation energy to break and form the appropriate bonds as well as have the correct orientation when colliding. If the favourable amount of collisions increase, then the rate of the reaction would increase. However, if the reactant particles do not collide frequently or collide with less energy than the activation energy, they bounce apart and the reaction would then proceed slowly or not at all.
