Answer

  Column I   Column II
(i) Mathematical expression for rate of reaction. (b) Rate law.
(ii) Rate of reaction for zero order reaction is equal to. (a) Rate constant.
(iii) Units of rate constant for zero order reaction is same as that of. (d) Rate of a reaction.
(iv) Order of a complex reaction is determined by. (c) Oder of slowest step.
Explanation:
  1. Mathematical expression for rate of reaction is known as rate law.
  2. Rate of reaction for zero order reaction is equal to rate constant r = k[A].
  3. Unit of rate of reaction is same as that or rate of reaction.
  4. Order of complex reaction is determined by rate of a reaction, which is slowest.
