Expert Answer:

Rate of reaction
Rate constant of reaction
i) It is the speed of the reaction at which the reactants are converted into the products at any moment of time.
i) It is constant of proportionality in the rate law expression.
ii) It depends upon the concentration of reactant species at that moment of time.
ii) It refers to the rate of reaction at the specific point when concentration of every reacting species is unity.
iii) It generally decreases as the reaction proceeds.
iii) It is constant and does not depend on the progress of the reaction.
