Heat of combustion of benzoic acid (C6H5...

Heat of combustion of benzoic acid `(C_6H_5COOH)` at constant volume at `25^@C` is `-3233KJ//"mole"`. When 0.5g of benzoic acid is burnt in bomb calorimeter, the temperature of calorimeter increased by `0.53^@C`. Now in the same bomb calorimeter 1g of `C_2H_6` burnt then temperature increased by `2.04^@C`. `DeltaH ` for combustion of `C_2H_6`is 

A

`-1530` KJ/mole

B

`-1536.2` KJ/mole

C

`-1522 .8KJ`/mole
