The diagrams here represent solutions at various stages in the titration of a weak base B (such as NH3) with HCl. Which image best represents the solution at the equivalence point?

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?
