- Q1Which of the following would NOT increase the rate of a chemical reaction?increasing the concentration of the productsincreasting the temperatureadding a catalystincreasing the surface area30sSC.912.P.12.12
- Q2How does adding a catalyst increase the rate of a reaction?Adding a catalyst lowers the activation energy required for a reaction to ocurrAdding a catalyst increases the concentration of the substances involved in a reactionAdding a catalyst increases the kinetic energy of the reactantsAdding a catalyst allows the substances to move slower and more carefully so the reaction proceeds more efficiently30sSC.912.P.12.12
- Q3Which of the following reaction systems will proceed most quickly? (assume all other factors are constant)System BSystem CSystem DSystem A30sSC.912.P.12.12
- Q4This potential energy diagram demonstrates which way to increase a reaction rate?Increasing surface areaIncreasing kinetic energyAdding a catalystIncreasing reactant concentration30sSC.912.P.12.12
