Question
ΔH of which of the following reaction(s) may be directly taken as enthalpy of combustion of the concerned substance?
Options
A.C(s) + O2(g) → CO2(g)
B.2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(l)
C.C3H8(g) +(7/2)O2(g) → 3CO(g) + 4H2O(l)
D.½ N2(g) + (1/2)O2(g) → NO(g)
Solution
One mole of the substance should burn completely.
