What is the difference between rate of reaction and reaction rate constant?

Difference between rate of reaction and reaction rate constant are as follows:

RATE OF REACTION

REACTION RATE CONSTANT

Rate of reaction is the change in concentration of a reactant or product per unit time. It is a constant of proportionality in the rate law equation and is equal to the rate of reaction when the molar concentration of each of the reaction is unity.
The rate of reaction at any instant of time depends upon the molar concentrations of the reactants at that time. The rate constant is constant for a particular reaction at a particular temperature and does not depend upon the concentrations of the reactants.
Its units are always moles litre<sub>-1</sub> time<sup>-1</sup> It units depend upon the order or reaction. A reaction is said to be of the zero order, first order, second order, and third order if some of concentration terms is equal to 0, 1, 2 and 3 respectively
