Question:

At some temperature, a 100-L reaction vessel contains a mixture that is initially 1.00 mol CO and 2.00 mol H2. The vessel also contains a catalyst so that the following equilibrium is
attained:

At equilibrium, the mixture contains 0.100 mol CH3OH. In a later experiment in the same vessel, you start with 1.00 mol CH3OH. How much methanol is there at equilibrium? Explain.
