1. Crcle the letter of each correct statement. a. A catalyst increases reaction speeds up by lowering the minimum energy needed for the reaction to occur. b. A catalyst is consumed during the reaction Equilibrium concentrations remain constant after adding a catalyst. d. Two reactant molecules that collide with enough kinetic energy will always produce products. The equilibrium constant is expressed as the ratio of the concentration of products over the concentration of reactants Reaction - Reaction 2. (6 Points) Use the energy diagrams above to answer this question. Reaction Ais and has a activation energy than reaction B. a. exothermic lower b. endothermic; lower e endothermic; the same a. exothermic; larger e. endothermic larger 3. (6 points) Asume a reaction has a K42x10. The equilibrium position can be describes as being favored towards the concentratilon of products is relatively a. products; small b. products; large C. neither direction, large d. reactants; large e reactants; small 1.
