The decomposition of copper(II) nitrate on heating is endothermic reaction. 2Cu(NO3)2(s) → 2C10(s) + 4NO2(g) + O2(g) Calculate t
he enthalpy change for this reaction using the following enthalpy changes of formation. AH! [Cu(NO3)2) = -302.9 kJ mol? AH, (CuO) = -157.3 kJ mol?. AH[NO2) = +33.2 kJ mol.
