A Rate Constant Is

Question

A rate constant is
A) the rate of a reaction at standard temperature and pressure.
B) the rate of a reaction at equilibrium.
C) a proportionality constant relating the rate of a reaction to the concentration(s) of the reactant(s).
D) a kind of transition state.

Accepted Answer

A rate constant is a proportionality constant that relates the rate of a chemical reaction to the concentration(s) of the reactants. It is not the rate of a reaction at standard temperature and pressure, not the rate of a reaction at equilibrium, and not a kind of transition state.
