Calculate K using the following concentrations of each substance at equilibrium:

C2H4 =0.090 M, Cl2 =0.24 M, C2H4Cl2 =0.090 M

Be sure your answer has the correct number of significant figures.

K=

K= [C2H4Cl2] / ([C2H4] x [Cl2])

K= (0.090) / (0.090 x 0.24)
K= 0.090 / 0.0216
K= 4.17

Therefore, K = 4.17
