Consider the reaction below. At 500 K, the reaction is at equilibrium with the following concentrations. [PCI5]= 0.0095 M [PCI3]
Dmitriy789 [7]

Answer: The equilibrium constant for the given reaction is 0.0421.

Explanation:

PCl_5\rightleftharpoons PCl_3+Cl_2

Concentration of [PCl_5] =  0.0095 M

Concentration of [PCl_3] =  0.020 M

Concentration of [Cl_2] =  0.020 M

The expression of the equilibrium constant is given as:

K_c=\frac{[PCl_3][Cl_2]}{[PCl_5]}=\frac{0.020 M\times 0.020 M}{0.0095 M}

K_c=0.0421 (An equilibrium constant is an unit less constant)

The equilibrium constant for the given reaction is 0.0421.
