Hi guys, I'm having trouble with this test review problem:

Methanol is produced commercially by the catalyzed reaction of carbon monoxide and hydrogen:
CO(g) + 2H2(g) --> CH3OH(g)

An equilibrium mixture in a 1.61L vessel is found to contain .0341 mol CH3OH, .120 mol CO and .215 mol H2 at 500K. Calculate Kc at this temperature.

I'd appreciate any suggestions. Thanks!

Start by writing the equilibrium mass action expression for the reaction

Find the concentrations of each compound (you have moles and volume)

then plug these into the expression, (how are the coefficients used?) and calculate Kc

Thank you! I did what you said and got the correct answer.
