The energy diagram is shown for an uncatalyzed, gas-phase reaction. The addition of a catalyst will Change both b and c by the same amount, but not change a. Decrease b and c, but will change b by a larger amount. Decrease a, b, and c by the same amount. A. 58 days B. 38 days C. 29 days D. 14 days 4. Collisions of insufficient energy do not result in chemical reaction.
Reaction rates increase in the presence of a catalyst because collision rates are increased.
The order of a reaction is determined by experiment. The order of a reaction is a positive integer. A first order reaction is also unimolecular. An increase in temperature increases the order of the reaction. M is prepared by the dilution of a stock solution.
