Question

why does methane have higher calorific value than ethane, eventhough ethane has higher proportion of hydrogen? [I'm reporting irrelevant answers :D]​

Answer 1

Answer:

Correct option is

B

Ethane

Calorific value is the amount of heat produced by complete combustion of 1 Kg of fuel,

so, in case of methane, 16g of methane produce −890.3Jmol

−1

amount of energy,

so, 1 Kg of metahne produce −55643.75Jmol

−1

in case of ethane, 28 g produce −1560Jmol

−1

amount of energy

so, 1 Kg of ethane produce enrgy = −55714.28Jmol

−1

hence, the energy produce by 1 Kg of ethane is mor than that of methane,

so, Ethane have higher calorific value

Answer 2

Explanation:

Calorific value is the amount of heat produced by complete combustion of 1 Kg of fuel,

so, in case of methane, 16g of methane produce −890.3Jmol

−1

amount of energy,

−1

amount of energy

so, 1 Kg of ethane produce enrgy = −55714.28Jmol

−1

hence, the energy produce by 1 Kg of ethane is mor than that of methane,

so, Ethane have higher calorific value.
