Planning Investigate the rate of reaction between HCl and Na2S2O3 Jackie Randall 10A For this piece of coursework we are investigating the rates of reaction and he effect different changes have on them. The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. We are studying the affect of changing concentration of Na2S2O3 Solution and dilute HCl. I believe these variables will affect the rate of reaction: * Surface area * Pressure * Temperature * Catalyst * Concentration Concentration If the concentration of a solution is increased there are more reactant particles per unit volume. This increased the probability of reactant particles colliding with each other. Pressure If the pressure is increased the particles in the gas are pushed closer. This increases the concentration and that will change the rate of reaction. Surface Area If a solid is powdered then there is a greater surface area available for a reaction,...
