The Effect Of Temperature On The Rate Of The Reaction

In reference to the collision theory, molecules act as small spheres that collide and bounce off each other, transferring energy among themselves when the collide. In order for a reaction to occur, there must be collisions between molecules. Through experimentation, factors are discovered that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, surface area, the physical state of reactants, and a catalyst. This experiment regarding the factors that affect reaction rate tests the effects of increased concentration and

The temperature can have a major impact on an enzyme. According to Campbell Biology author Reece etc. 2011 “The enzyme reaction will increase as the temperature increase with the increasing temperature….substrates collide with active sites more frequently when the molecules move rapidly.”(Reece etc 2011) Every enzyme hits its optimal temperature the reaction will be at its highest point.(Reece etc. 2011) When the

Temperature controls the speed the enzymes work at. Higher temperatures increase the kinetic energy which increases the chance of collision therefore speeding up the rate of

As the temperature increases, so will the rate of enzyme reaction. However, as the temperature exceeds the optimum the rate of reaction will decrease.

Many factors effect reaction rates, two shown above include temperature and concentration. Concentration affects the rate of reactions because the more concentrated a solution the more likely collisions between particles will be. This is simply because there are more particles present to collide with each other. When the temperature is higher, particles will

Abstract: This two part experiment is designed to determine the rate law of the following reaction, 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L), and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1, and the experimental activation energy is 60.62 KJ/mol.

Usually an increase in temperature in a chemical reaction means that there will be an increase in the reaction rate of the reactants. Temperature is a measure of the kinetic energy of a system. If temperature is the measure of the kinetic energy of a system, higher temperature implies a higher average kinetic energy of molecules and more collisions per time. This would happen because when the temperature is increased and the reactants will start moving faster and will collide more than before with other reactants and will start forming products.

Hypothesis: If the temperature increases, then rate of the chemical reaction will increase as well, and if the temperature decreases, then the rate of reaction will also decrease.

Hypothesis: If the temperature (I.V.) of materials in the reaction are increased, the reaction time (D.V.) will decrease.

Secondly: The samples were only placed in the water bath for five minutes and as soon as any samples were removed the temperature

Temperature does have an effect on reaction rate, it has a major impact on reaction rate because as it increases collisions between substrates and active sites occur more frequently as molecules move

If the acid is made more concentrated there are more particles, which means collisions are more likely. So, the higher the concentration, the quicker the reaction time is. Temperature also affects the rate of reaction. If the temperature is increased, the particles move quicker so more collisions happen. This means the higher the temperature, the

reaction rate increases. If the temperature of an enzyme gets to high the reaction rate will slow
