Expert Solution

Step 1

Rate constant: It is a proportionality constant that give direct relation between rate of reaction and concentration of reactant. It is denoted by k and its unit is dependent on order of reaction.

Arrhenius equation has a major application in study of chemical kinetics. This relation is used to obtained rate constant at given temperature with the help of rate constant at different temperature and activation energy.
