Title: How to increase the Rates of a chemical reaction 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

Aim: The rate at which a reaction occurs, or takes place, is affected by various factors, such as the temperature at which the experiment is conducted in, the pressure which is given, the surface area which is exposed, use of catalysts, and the concentration. In this investigation, I would be investigating the affect of surface area, or particle size, in the rate at which a reaction occurs. Background Information: The more finely divided the solid is, the faster the reaction happens. A powdered

Chemistry Coursework – Rates of Reaction Investigation Introduction In this investigation I am going to be investigating the reaction between marble chips and hydrochloric acid, and to see what differences in the rate of this reaction arise when different concentrations of acid are used. Below is the word equation for this reaction: Calcium Carbonate + Hydrochloric Acid = Calcium Chloride + Carbon Dioxide + Water Below is the fully balanced chemical equation for this reaction.

Chemistry IA Title : The relationship between the temperature and the rate of reaction in a chemical reaction. Introduction : Last academic year, towards the end, in IB chemistry hl class, my class had the chance to learn about the concentration, temperature, catalysts, etc and their effects on the rate of reaction in a chemical reaction. I knew that the rate of reaction had a relationship with the factors but I wanted to know how it changes witness it for myself. I wanted to perform an experiment

Introduction A chemical reaction is when two or more (different) substances, react with each other to form new chemical substances(product). In a chemical reaction, the molecular structure is rearranged.When the molecular structure is rearranged it can increased or decreased. The signs of a chemical reaction include a colour change, temperature change, formation into a gas and odour change. The rate of reaction can be increased by increasing the temperature, concentration and the expansion of the

Effect of Reactant Concentration on Reaction Rate 16/01/2017 Aim: To investigate the effect of the concentration of Sodium Thiosulfate and Hydrochloric Acid and to determine the rate of the reaction. Introduction: Different reactant have different rate on reaction. Some may occur in a sudden; some can take hours to react. This experiment is to investigate how the reactant concentrations have an effect on the reaction rate. The reaction equation of Sodium Thiosulfate and Hydrochloric Acid:

Reactions occur everywhere, and they may take decades, such as fossils, or only seconds, such as lighting a match to occur. “Chemical kinetics concerns the rates of chemical reactions” and what factors affects these rates (Iodine Clock, 2017). “Temperature, concentration, pressure of reacting gases, surface area of reacting solids and the use of catalysts are all factors which affect the rate of a reaction” (Bbc.co.uk, 2017). This is because they affect the reaction roles and yields of activation

this will result will be a slower rate of reaction. Therefore, it is also hypothesised that the addition of a catalyst will cause the rate of those reactions to speed up, was proven correct by the results of this experiment, in that the changing of the concentration and the addition of a catalyst changed the speed at which the reaction occurred. The results from both Part 1 and Part 2 conclusively showing that the have a direct effect on the rate at which the reaction occurs. In order to come to this
