QUESTION: 16

Heat of combustion ΔH for C(s), H2(g) and CH4(g) are -94, -68 and -213 cal/mol. Then ΔH for C(s) + 2H2(g) → CH4(g) is

Solution:

CH4 + 2O2 = CO2 + 2H2O
ΔH = -213 cal/mol .....(1)
C + O2 = CO2
ΔH = - 94 cal/mol .....(2)
H2 + (1/2) O2 = H2O
ΔH = - 68 cal/mol .....(3)
ΔH for C(s) + 2H2(g) → CH4(g)
= 2(eq 3) + (eq 2) - (eq 1)
= (- 68 x 2) + (- 94) - (- 213) = -17Kcal
