(1) C + O2 → CO2, 
= -286 kJ/mol
(2) H2 + O2 → H2O,
= -393.5 kJ/mol
(3) C2H6 + O2 → 2CO2 + 3H2O,
= -1560 kJ/mol
Calculation:
2 × (1) + 3 × (2) - (3)
2C + 3H2 C2H6
(C2H6) = 2(-286) + 3(-393.5) + 1560 = -192.5 kJ/mol
= -286 kJ/mol(2) H2 + O2 → H2O,
= -393.5 kJ/mol(3) C2H6 + O2 → 2CO2 + 3H2O,
= -1560 kJ/molCalculation:
2 × (1) + 3 × (2) - (3)
2C + 3H2 C2H6
(C2H6) = 2(-286) + 3(-393.5) + 1560 = -192.5 kJ/molAttention JEE Students!
