Methane gas can be produced by the reaction of solid carbon with hydrogen gas as follows                     C(s)   +   2 H2(g)  ⇌   CH4(g) For this reaction at equilibrium, Kp =  0.38.  A vessel containing carbon is sealed and injected inititally with hydrogen to a pressure of 2.0 atm and with methane to a pressure of 2.0 atm. What happens as the reaction proceeds toward equilibrium?  Hint:  this is a K vs Q question.  Which way will the reaction proceed to reach equilibrium?
