QUESTION
Calculate H 298 (in kJ) for the process P( s ) + 5/2 Cl 2 ( g ) PCl 5 ( g ) from the following information.
Calculate ΔH⁰298 (in kJ) for the process P(s) + 5/2 Cl2(g) → PCl5(g) from the following information.
P(s) + 3/2 Cl2(g) → PCl3(g) ΔH⁰298 = −287 kJ PCl3(g) + Cl2(g) → PCl5(g) ΔH⁰298 = −88 kJ
