Although nitrogen trifluoride (NF3) is a thermally stable compound, nitrogen triiodide (NI3) is known to be a highly explosive material. NI3 can be synthesized according to the equation BN(s) + 3 IF(g) → BF3(g) + NI3 (8) a. What is the enthalpy of formation for NI3 (s) given the enthalpy of reaction (-307 kJ) and the enthalpies of formation for...
