NEET Physics (general) Match the Following Question
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
Choose the correct matching:
a-i, b-iii, c-ii, d-iv
a-iv, b-ii, c-iii, d-i
a-iii, b-iv, c-i, d-ii
a-ii, b-i, c-iv, d-iii
Correct Answer
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.
