6 of 15 A student observes that the reaction rate of the catalyzed reaction A→B+C is unaffected by adding extra catalyst. Which conclusion is correct? The rate law must be first order. The rate is unaffected since the catalyst's effect is part of k. O The reaction probably is more likely to go in reverse than the forward direction. The temperature needs to be increased to make the catalyst work better. 7 of 15 A student states that the higher the surface area, the faster will be a chemical reaction rate. Which statement below is perhaps a more accurate way to say this? The higher the reactant surface area, the faster the reaction rate. The greater the surface area per volume reactant, the faster the reaction rate. More surface means more reaction. Surface area affects chemical reactions.
