NEET Chemistry (general) Match the Following Question
Type: Match the Following-match the column-Hard-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Strongly endothermic reaction | (i) Large and positive ∆ r H |
| (b) Exothermic reaction | (ii) K much smaller than 1 |
| (c) ∆ r G in exothermic reactions | (iii) K much larger than 1 |
| (d) Positive ∆ r S | (iv) Reaction likely to form products |
A
a-i, b-iii, c-ii, d-iv
B
a-ii, b-iii, c-i, d-iv
C
a-i, b-ii, c-iii, d-iv
D
a-i, b-iii, c-iv, d-ii
Correct Answer
Option A
Detailed Explanation
Strongly endothermic reactions have a large and positive ∆ r H, leading to a K value that is much smaller than 1, indicating that product formation is unlikely. In contrast, exothermic reactions have a large and negative ∆ r H, resulting in a K value much larger than 1, suggesting that these reactions can proceed to near completion.
