(2) 1.2 Which one of the options below is the best description of reaction rate for the following reaction? Zn is the limiting reactant. Zn(s) + 2HCℓ(aq) → ZnCℓ2(aq) + H2(g) The reaction rate is… A. the time it takes to use up all the reactants. B. the decrease in concentration of the Zn per time unit. C. the time it takes for HCℓ(aq) to be used up. D. the change in the volume of H2 over a certain period of time. (2) 1.3 The Maxwell–Boltzmann distribution curve for a reaction mixture is shown below. The TEMPERATURE of the reaction mixture is now REDUCED. Which one of the following shows the new distribution curve as a dashed line? (2) 1.4 Consider the reaction represented by the following balanced chemical equation. The system is initially in equilibrium. H2(g) + Br2(g) ⇌ 2HBr(g) The pressure is increased by reducing the volume of the container at constant temperature. How will the amount of HBr and the concentration of HBr change as a result of this increase in pressure? Quantity HBr Concentration of HBr A. Increase Increase B. Decrease Decrease C. Stay the same Increase D. Stay the same Decrease (2) 1.5 The reaction represented by the balanced chemical equation below was used to investigate how certain factors affect the reaction rate.
