Consider the following reaction.

C2H4(g) + Cl2(g)= C2H4Cl2 (g)

Part 1 of 2

Write the expression for the equilibrium constant for this reaction.

K=

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

[C2H4]=0.090 M, [Cl2]=0.36 M, [C2H4Cl2]=0.135 M

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

K=

1 answer

K = [C2H4Cl2] / ([C2H4] * [Cl2])
K = 0.135 / (0.090 * 0.36)
K = 0.135 / 0.0324
K = 4.17

Therefore, K = 4.17.
