Question

A quantity of 1.6 g sample of $	ext{NH}_4	ext{NO}_3$ is decomposed in a bomb calorimeter. The temperature of the calorimeter decreases by 6.0 K. The heat capacity of the calorimeter system is 1.25 kJ/K. The molar heat of decomposition for $	ext{NH}_4	ext{NO}_3$ is

Prashant Kotian · Accepted Answer

Correct answer: D. Molar mass of = . Moles decomposed = . Heat absorbed by the reaction from the calorimeter . Molar heat = . (Since temperature decreases, the reaction is endothermic and thus positive).
