Nitroglycerin is shock sensitive, and decomposes explosively: 4C3H5N3O9(l) → 12CO2(g) + 6N2(g) + O2(g) + 10H2O(g)
ΔHf° -370 -393.5 -241.8
a. What is the molar enthalpy of decomposition (detonation) of nitroglycerin?
b. Calculate the change in internal energy (ΔU) that occurs when 4 moles of nitroglycerin are detonated at 25°C.
