Match the entries of column I with appropriate entries of column II and choose the correct option out of the four options given.
| Column I | Column II |
| (i) Mathematical expression for rate of reaction | (a) rate constant |
| (ii) Rate of reaction for zero order reaction is equal to | (b) rate law |
| (iii) Units of rate constant for zero order reaction is same as that of | (c) order of slowest step |
| (iv) Order of a complex reaction is determined by | (d) rate of a reaction |
Answer & explanation
Correct answer: option 2
(i) Rate law is the mathematical expression for rate of reaction.
(ii) Rate of reaction for zero order reaction is equal to rate constant.
For e.g., If A → B is a zero-order reaction,
r = k[A]0 = k
(iii) Units of rate constant for zero order reaction is same as that of rate of a reaction.
(iv) Order of a complex reaction is determined by order of slowest step.
