Rates of reaction questions

IB Chemistry: Rates of reaction questions

1. Define the term rate of reaction.2. Explain why the rate of a chemical reaction generally decreases as the reaction proceeds.3. The graph below shows the volume of hydrogen evolved against time for the reaction of a piece ofsolid magnesium metal with 1.00 mol dm-3 hydrochloric acid, HCl(aq).Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)(a) Deduce the rate of the reaction at time t = 1.5 minutes.
