| Column-I | Column-II |
|---|---|
| (a) Standard molar enthalpy of formation | (i) H2 gas |
| (b) Reference state of oxygen | (ii) 0 |
| (c) Enthalpy of combustion of methane | (iii) -890.3 kJ mol-1 |
| (d) Enthalpy of combustion of graphite | (iv) -393.5 kJ mol-1 |
a-i, b-ii, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-i, c-iii, d-iv
a-i, b-iv, c-ii, d-iii
Correct Answer
Detailed Explanation
The standard molar enthalpy of formation is represented as ∆fH° where its reference states include H2 gas for dihydrogen, and the enthalpy of combustion for methane is -890.3 kJ mol-1 while that of graphite is -393.5 kJ mol-1.
