Question

Calculate the ΔH^o for methane gas , CH4, produced from graphite and hydrogen gas according to the following reaction: C_(graphite) + 2H₂(g) à CH₄(g)

Data given:

C_(graphite) + O₂(g) à CO₂(g) ΔH^o= -393.5 kJ
H₂(g) + ½ O₂(g) à H₂O(l) ΔH^o= - 285.8 kJ
CH₄(g) + 2O₂(g) à CO₂(g) + 2H₂O(l) ΔH^o = -890.4kJ
