Question:

A 4.72- g sample of methanol (CH3OH) was placed in an otherwise empty 1.00- L flask and heated to 250oC to vaporize the methanol. Over time the methanol vapor decomposed by the following reaction:
CH3OH(g) ⇌ CO(g) + 2H2(g)
After the system has reached equilibrium, a tiny hole is drilled in the side of the flask allowing gaseous compounds to effuse out of the flask. Measurements of the effusing gas show that it contains 33.0 times as much H2(g) as CH3OH(g). Calculate K for this reaction at 250oC.
