Consider the reaction 3X + Y ⇔ 2W + Z.
At equilibrium, [X] is 7.0 M, [Y] is 6.0 M, [W] is 5.0 M and [Z] is 7.0 M at 298 K. The value of the equilibrium constant at this temperature is:
a) 0.085
b) 0.560
c) 1.800
d) 11.760

Write the Keq expression, substitute the values given and solve for Keq. Post your work if you have questions.
