k stands for in chemistry

The Arrhenius equation, \[k = A e^{-E_a/RT} \tag{1}\] can be written in a non-exponential form that is often more convenient to use and to interpret graphically. The rate law is expressed as, Rate = k[A]x[B]y, where k is the rate constant; x and y are the rate orders with respect to individual reactants.
