Question

For the decomposition reaction PCl5(g)⇌PCl3(g)+Cl2(g), if the equilibrium concentrations are [PCl5]=1.0M,[PCl3]=0.10M,[Cl2]=0.10M, what is the value of the equilibrium constant?

O 1.0 x 10^2
O 1.0 x 10^-2
O 2.0 x 10^-2
O 1.0 x 10^-4

Answer 1

B

Step-by-step explanation:

Kq=[PCl3][Cl2]/[PCl5]=[0.1M][0.1M]/[1M]=1×10^-2
