Chemistry - Thermodynamics - I Question with Solution | TestHub

1 gram sample of ${\mathrm{NH}}_4{\mathrm{NO}}_3$ is decomposed in a bomb calorimeter. The temperature of the calorimeter decreases by 6 K . The heat capacity of the calorimeter is $1.25\mathrm{KJ}{\mathrm{K}}^{-1}$. What is the molar heat of decomposition of ${\mathrm{NH}}_4{\mathrm{NO}}_3$ ?

$${\mathrm{NH}}_4{\mathrm{NO}}_3\left(s\right)\to N_{2}O\left(g\right)+2H_{2}O\left(g\right)$$
