Question

The heat of combusion of benzne determined in a bomb calorimeter is `-870Kcal mol^(-1)` at `298 K`. The value of `DeltaE` for the reaction is
A. `-1740 kcal mol^(-1)`
B. `+870 kcal mol^(-1)`
C. `-870 kcal mol^(-1)`
D. `+1740 kcal mol^(-1)`

Answer 1

Correct Answer - C
The heat change determined in a bomb valorimeter is `DeltaE` value. Thus
`DeltaE=-870kcal mol^(-1)`
