Application +4 | -1

In a 500 mL flask, the degree of dissociation of

\mathrm{PC}{\mathrm{l}_5}

at equilibrium is

40\%

and the initial amount is 5 moles. The value of equilibrium constant in

\mathrm{mol}\;{\mathrm{L}^{ - 1}}

for the decomposition of

\mathrm{PC}{\mathrm{l}_5}

View answer and explanation

Correct option: B

2.66

Option B (2.66) is correct because the equilibrium constant is calculated based on the degree of dissociation and the initial amount of PCl5.
