The values of heat of combustion of ethane (C 2 H 6 ) and ethyne (C 2 H 2 ) are –341 and –310 Kcal respectively. Then which of the following is better fuel on mass basis :
Text Solution
Verified by ExpertsThe correct answer is:
A
Calorific value = 
for ethane (C 2 H 6 ) = – 
= –11.37
for ethyne (C 2 H 2 ) = – 
= –11.9
So, better calorific value is better fuel hence, C 2 H 2 .
