Type: Match the Following-match the column-Medium-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Standard Molar Enthalpy of Formation | (i) Reaction at constant temperature and pressure |
| (b) Exothermic Reaction | (ii) Energy absorbed in breaking bonds |
| (c) Endothermic Reaction | (iii) Negative enthalpy change |
| (d) Hess's Law | (iv) Total enthalpy change is path independent |
A
a-i, b-iii, c-ii, d-iv
B
a-iv, b-ii, c-iii, d-i
C
a-iii, b-iv, c-i, d-ii
D
a-ii, b-i, c-iv, d-iii
Correct Answer
Option A
Detailed Explanation
The standard molar enthalpy of formation refers to the enthalpy change when one mole of a compound is formed from its elements in their standard states. Exothermic reactions have a negative enthalpy change, while endothermic reactions absorb energy. Hess's Law states that the total enthalpy change is independent of the pathway taken.
