Question

1. What parameter must remain the same for k to be a constant in the rate law equation? a) temperature b) pressure c) volume d) activation energy

2. Which is not an important characteristic of elementary processes?
a) certain intermediates are produced in one elementary process and consumed in another
b) conc' exponents in rate eq' for an elementary process are the same as the coefficients in the balanced eq' of the process.
c) some elementary processes may reach a condition of equilibrium in which the rates of the fwd 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

1 a) temprature must remain constant

2) D, it is the slow reactions that determine the overall rate of the reaction
