Question

TNT is a highly explosive compound. The thermal decomposition of TNT is described by the following equation:

2 C7H5N3O6(s) --------> 12 CO(g) + 5 H2(g) + 3 N2(g) + 2 C(s)

_______________ g TNT

TNT is a highly explosive compound. The thermal decomposition of TNT is described by the following equation: 2 C7H5N3O6(s) --------> 12 CO(g) + 5 H2(g) + 3 N2(g) + 2 C(s) The enthalpy change for the explosion of ammonium nitrate with fuel oil is -7198 kJ for 3 moles of NH4NO3. If DeltaHrxn for the thermal decomposition of 2 moles of TNT is -20,306 kJ, how much TNT is needed to equal the explosive power of 1 mole of ammonium nitrate? _______________ g TNT

Explanation / Answer

Supposing "explosive power" to be proportional to ?H (which it probably isn't, really):

(1 mol NH4NO3) x (7198 kJ / 3 mol NH4NO3) = 2399 kJ from NH4NO3

(2399 kJ) / (20306 kJ / 2 mol C7H5N3O6) x (227.1311 g C7H5N3O6/mol) = 53.67 g C7H5N3O6
