Answer to Question #82006 in General Chemistry for Manvir Nahal

Question

Given the following enthalpy change values for the reactions below:

A + B → 2C ; ΔH = 286.5 kJ mol-1

C + 2D → E + F ; ΔH = 41.8 kJ mol-1

H → ½ E + G ; ΔH = 373.9 kJ mol-1

Calculate ΔH for the following reaction (in kJ mol-1) using Hess's Law:

A + B + 4D + 4G → 4H + 2F
