During complete combustion of one mole of butane, 2658 kJ of heat is released. The thermochemical reaction for above change is

Reason: -

A. As it is provided that there is combustion of 1 mole of butane.


B. The heat released during the combustion of butane is 2658 kJ.


C. In this reaction, there is a combustion of 1 mole of butane and the energy released is 2658 kJ.


D. In this reaction, there is also combustion of 1 mole of butane but the sign of ΔcH is positive, which is indicating that we have given that much amount of energy.
