1. a) True or False? For a reaction at equilibrium, the value of AG is 0, which means that the process is not spontaneous in either direction. b) True or False? Catalysts accelerate chemical reactions by changing the mechanism and lowering E,, but they are consumed or destroyed in the process. c) True or False? Enzymes (like alcohol dehydrogenase, which removes ethanol from our bodies) universally show zero order kinetics. d) True or False? For a reaction to be successful, molecules must collide with appropriate activation energy (E,), but their orientation with respect to one another is not important. e) True or False? The collisional frequency for 2 reactants increases as their concentration decreases.
