18. Consider the hypothetical reaction: A+2B 2C + D The mechanism for the reaction is 2874 fast equibrium slow Which one of the reaction profiles shown below fits this mechanism? A. B. Reaction progress Reaction progress C. D. /LA Reaction progress Reaction progress E. There is not enough information to choose 24. Rick T. Cat needs golden claws for his next great adventure across the deserts of Caldeum and he needs them fastl He decides to use a 60 ampere current to reduce his solution of Au(NO h into solid gold How long ill it take him to plate 10 grams of gold for his next amazing adventure? A. 148 sec B. 245 sec C. 14,700 sec D. 48,250 sec E. 882,000 sec

Explanation / Answer

A.

Because the reaction mechanishm as shown tells us that the reaction is happening in two steps and as the second step is slow, it is the rate determining step and thus the energy taken to complete that step would be more than that of the first step.Hence, the graph will have two distinct maximum values of energy and one internmediate, and first step would require less energy and second step would require more energy.HENCE the answer is option A.
