Answer 1

Explanation:

The enthalpy of fusion of water is 1.435 kcal/mol. The molar entropy change for the melting of ice at 0°C is

Consider the reaction :

4NO2(g) + O2(g) ® 2N2O5(g), ΔrH = –111kJ.

If N2O5(s) is formed instead of N2O5(g) in the above reaction, the ΔrH value will be:

(given, ΔH of sublimation for N2O5 is 54 kJ mol–1)

Based on the first law of thermodynamics, which one of the following is correct
