• A)K_P = \(\frac { \mathrm { P } ^ { 2 } \left( \mathrm { PCl } _ { 3 } \right) } { \mathrm { P } ^ { 2 } ( \mathrm { P } ) \times \mathrm { P } ^ { 3 } \left( \mathrm { Cl } _ { 2 } \right) }\)
• B)K_P = \(\frac { \mathrm { P } ^{1 / 2} \left( \mathrm { PCl } _ { 3 } \right) } { \mathrm { P } ^{1 / 2} ( \mathrm { P } ) \times \mathrm { P } ^ { 1 / 3 } \left( \mathrm { Cl } _ { 2 } \right) }\)
• C)K_P = \(\frac { \mathrm { P } \left( \mathrm { PCl } _ { 3 } \right) } { \mathrm { P } ( \mathrm { P } ) \times \mathrm { P } ^ { 3 / 2 } \left( \mathrm { Cl } _ { 2 } \right) }\)
• D)K_P = \(\frac { \mathrm { P } ^ { 2 } ( \mathrm { P } ) \times \mathrm { P } ^ { 3 } \left( \mathrm { Cl } _ { 2 } \right) } { \mathrm { P } ^ { 2 } \left( \mathrm { PCl } _ { 3 } \right) }\)
• E)K_P = \(\frac { \mathrm { P } ( \mathrm { P } ) \times \mathrm { P } ^ { 3 / 2 } \left( \mathrm { Cl } _ { 2 } \right) } { \mathrm { P } \left( \mathrm { PCl } _ { 3 } \right) }\)
