The enthalpy change for the reaction F2(g) + 2HCl(g) → 2HF(g) + Cl2(g) at 298 K is -357.6 kJ mol-1. If the standard enthalpy of formation \(\left[\Delta H_{f}^{a}\right]\) of \(\text { HCI }\) is -92.3 kJ mol-1, the \(\Delta H_{f}^{a}\) of HF at 298 K is:
- - 265.3 kJ mol-1
- + 265.3 kJ mol-1
- - 224.9 kJ mol-1
- - 271.1 kJ mol-1
Answer
(D) - 271.1 kJ mol -1
