| Column-I | Column-II |
|---|---|
| (a) Standard Enthalpy of Vaporization | (i) 25.2 kJ mol –1 |
| (b) Lattice Enthalpy of NaCl | (ii) +40.79 kJ mol –1 |
| (c) Standard Enthalpy of Sublimation | (iii) +788 kJ mol –1 |
| (d) Standard Enthalpy of Formation | (iv) Reference state at 25°C |
a-ii, b-iii, c-i, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-iii, d-i
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The standard enthalpy of vaporization (∆ vap H ) for water is +40.79 kJ mol –1, the lattice enthalpy of NaCl is +788 kJ mol –1, and the standard enthalpy of sublimation for solid CO2 is 25.2 kJ mol –1, matching with their respective pairs.
