1. Kinetics - graphs Sketch volume-time graphs for: 1.hydrogen produced during a magnesium and hydrochloric acid reaction both reactants are in stoichiometric ratio’s 2.same reaction carried out with a twice as concentrated acid solution (acid in excess) 3.same reaction as 1 but carried out with a twice as concentrated acid solution (acid as limiting reagent) 4.the first reaction carried out with half the acid concentration but the acid as the limiting reagent

2. Kinetics - graphs Sketch mass-time graphs for: o Mass of flask + contents when hydrochloric acid reacts with calcium carbonate (=limiting reagent). o Show how you would determine the initial rate of the reaction o Mass of CO 2 produced during same reaction. o On the above graph, add a line showing change in mass of CO 2 with greater surface area/smaller particles of CaCO 3.

3. Kinetics - graphs Sketch temperature-time graph for sodium thiosulphate and HCl reaction. Sketch a volume-time graph for oxygen production during decomposition of hydrogen peroxide: o without a catalyst o with liver o with chopped up liver
