The heat of combustion of benzene determined in a bomb calorimeter is - 870 kcal `mol^(-1)` at `25^(@)C`. The value of `DeltaE` for the reaction is

A

`-1740` kcal

B

`- 870` kcal

C

`-872` kcal

D

`-874` kcal

Text Solution

Verified by Experts

The correct Answer is:

B

Since the reaction happens in a bomb calorimeter at a constant volume so `Delta E` represents the heat of combustion. `Delta E= -870` kcal
