Question

One gram sample of NH 4 ​ NO 3 ​ is decomposed in a bomb calorimeter. The temperature of the calorimeter increases by 6.12 K . The heat capacity of the system is 1.23 kJ / g / deg . What is the molar heat of decomposition for NH 4 ​ NO 3 ​ ?

TestHub · Accepted Answer

Heat of decomposition, Δ E = m s Δ T = 1 × 1.23 × 6.12 = 7.5276 kJ . Molar heat of decomposition for NH 4 ​ NO 3 ​ = 7.5276 × 80 = 602.2 kJ / mol
