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:

[C2H2]= 0.180 M, [H20]= 0.36 M, [C2H40]= 0.270 M
Be sure your answer has the correct number of significant figures.

K=

1 answer

K= [C2H4] / [C2H2] * [H2O]

K= (0.270) / (0.180) * (0.36)

K= 0.54 (to 2 significant figures)
