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 ...

The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from...

How concentration affects reaction rate. The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the ...

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 ...

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...
