NEET Chemistry Order of Reaction Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Half-life of first-order reaction | (i) Independent of initial concentration |
| (b) Time for 90% completion | (ii) Dependent on concentration |
| (c) Time for 99% completion | (iii) Twice the time for 90% completion |
| (d) Rate constant k | (iv) Related to slope of ln[R] vs t plot |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The half-life of a first-order reaction is constant and independent of the initial concentration (i). The time required for 99% completion is indeed twice the time required for 90% completion (iii). Thus, option A is the correct match.
