Question
1. Which is not an important characteristic of elementary processes?
A. Certain intermediates are produced in one elementary process and consumed in another.
B. Concentration exponents in rate equation for an elementary process are the same as the coefficients in the balanced equation of the process.
C. Some elementary processes may reach a condition of equilibrium in which the rates of the forward and reverse processes are equal.
D. One elementary process may occur much more quickly than all the others in the reaction mechanism, and in all cases, determine the rate of the overall reaction.
Explanation / Answer
D. One elementary process may occur much more quickly than all the others in the reaction mechanism, and in all cases, determine the rate of the overall reaction
(Note: Always, the slowest step determines the rate of the overall reaction.)
