One gram sample of `NH_(4)NO_(3)` is decomposed in a bomb calorimeter. The temperature of the calorimeter increases by `6.12K` . The heat capacity of the system is `1.23KJ//g//deg` . What is the molar heat of decomposition for `NH_(4)NO_(3)` ?

A

`-7.53 kJ mol^(-1)`

B

`-398.1 kJ mol^(-1)`

C

`-16.1 kJ mol^(-1)`

D

`-602 kJ mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Delta U = -6.12 xx 1.23 xx GM M_(NH_(4)NO_(3))= - 6.12 xx 1.23 xx 80 = -602 kJ//mol`
