BACKGROUND INFORMATION What affects the rate of reaction? 1) The surface area of the magnesium. 2) The temperature of the reaction. 3) Concentration of the hydrochloric acid. 4) Presence of a catalyst. In the experiment we use hydrochloric acid which reacts with the magnesium to ...

Chemistry Coursework Rate of reaction Aim: Plan an investigation into the rate of reaction between Sodium thiosulphate and hydrochloric acid. Background information: • The equation for the rate of reaction is 1/time. • The rate of reaction measures the speed of reaction. It is ...

Introduction In this investigation I am trying to find out whether or not the concentration of hydrochloric acid affects the rate of reaction. To do this we are going to make up different concentrations of hydrochloric acid starting with 100% and working our way to 20%. Prediction I predict th...

Title: determination of the rate equation Task: Plan design and conduct an experiment to determine the rate equation for the reaction between Sodium Thiosulphate Na2S2O3 and Hydrochloric Acid HCl 2HCl(aq) + Na2S2O3(aq) 2NaCl (aq) + SO2(g) + S(s) + H2O(l) Equipment, apparatus and...
