NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Easy-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Exothermic Reaction | (i) K much smaller than 1 |
| (b) Endothermic Reaction | (ii) K much larger than 1 |
| (c) Standard Molar Enthalpy of Formation | (iii) ∆ f H |
| (d) Spontaneous Process at Low Temperature | (iv) ∆ r H < 0 |
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iii, d-iv
C
a-ii, b-i, c-iv, d-iii
D
a-ii, b-i, c-ii, d-iv
Correct Answer
Option A
Detailed Explanation
Exothermic reactions typically have a large equilibrium constant (K > 1), while endothermic reactions have a small K (K < 1). The standard molar enthalpy of formation is denoted by ∆ f H . In spontaneous processes at low temperature, reactions with negative enthalpy change (∆ r H < 0) occur.
