NEET Chemistry Enthalpy Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Exothermic Reaction | (i) +33.2 kJ mol –1 |
| (b) Endothermic Reaction | (ii) -285.8 kJ mol –1 |
| (c) Standard Enthalpy of Formation | (iii) 128.5 kJ mol –1 |
| (d) Enthalpy Change for Ionization | (iv) E0 (ionization energy) + 5/2 RT |
a-ii, b-i, c-iii, d-iv
a-ii, b-iii, c-i, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-iii, d-i
Correct Answer
Detailed Explanation
In an exothermic reaction like the formation of water, the enthalpy change is negative, as indicated by -285.8 kJ mol –1. Additionally, the endothermic reaction of nitrogen and oxygen to form nitrogen dioxide has a positive enthalpy change of +33.2 kJ mol –1.
