The balanced chemical equation for the reaction is given. 2 CH 3 NO 2 (l) + 3/2

Question

The balanced chemical equation for the reaction is given.

2 CH3NO2 (l) + 3/2 O2 ------> 2 CO2 (g) + 3 H2O (g) + N2 (g); H0rxn = -1418 kJ

The above statement should read the heat released for reaction of 2 mole(s) of nitromethane.

Molar mass of CH3NO2 = (1*12.01 + 3*1.008 + 1*14.0067 + 2*15.9994) g/mol = 61.0395 g/mol.

Mole(s) of CH3NO2 corresponding to 6.39 kg = (6.39 kg)*(1000 g/1 kg)*(1 mole/61.0395 g) = 104.6863 mole.

Heat released corresponding to reaction of 104.6863 mole CH3NO2 = (-1418 kJ)*(104.6863 mole/2 mole) = -74222.5867 kJ (ans).

Explanation / Answer

Part A Nitromethane (CH3NO2) burns in air to produce significant amounts of heat. 2CH3 NO2 (I) + 3/22 (g) 2CO2(g) 3H2O(g)N2 (g) Arron =-1418 kJ How much heat is produced by the complete reaction of 6.39 kg of nitromethane?
