NEET Chemistry Order of Reaction Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) First order reaction time for 90% completion | (i) Equal to half-life |
| (b) First order reaction time for 99% completion | (ii) Twice the time for 90% completion |
| (c) Half-life of a first order reaction | (iii) Independent of initial concentration |
| (d) Rate constant of zero order reaction | (iv) Dependent on concentration |
a-ii, b-i, c-iii, d-iv
a-iii, b-ii, c-i, d-iv
a-ii, b-iv, c-i, d-iii
a-i, b-iii, c-ii, d-iv
Correct Answer
Detailed Explanation
For a first order reaction, the time required for 99% completion is indeed twice the time required for 90% completion, as established in the examples of first order reactions. The half-life is independent of the initial concentration, affirming the characteristics of first order reactions.
