문제 3

Phosphorus trichloride is formed when diphosphorus reacts with chlorine gas. The reaction equation is P2 + 3 Cl2 → 2 PCl3. Calculate the ΔH for the reaction (in kcal and in kJ) using the bond dissociation energies in the table below.
Table showing average bond enthalpy values for P≡P, Cl–Cl, and P–Cl in kcal and kJ.
