# Problem: Using values from Appendix C in the textbook, calculate the standard enthalpy change for each of the following reactions.N2O4(g) + 4 H2(g) → N2(g) + 4 H2O(g)

###### FREE Expert Solution

We are asked to calculate the value of ΔH˚ for N2O4(g) + 4 H2(g) → N2(g) + 4 H2O(g)

Note that we need to multiply each ΔH˚ by the stoichiometric coefficient since ΔH˚ is in kJ/mol.

Balanced reaction : N2O4(g) + 4 H2(g) → N2(g) + 4 H2O(g)
