Which of the following has highest heat of combustion out of the following and why?
(a) C2H6 (b) C2H4 (c) C2H2 (d) CH4
Which of the following has highest heat of combustion out of the following and why?
(a) C2H6 (b) C2H4 (c) C2H2 (d) CH4
C2H6(g) will have highest heat of combustion because it has highest molecular weight and second highest calorific value.
ΔHc = calorific value of kJ/g × mol. wt. = 52 × 30 = 1560 kJ/mol.
