Solution: The  equilibrium constant for the reaction                               2 H   2 (g)  +   CO (g) ⇌ CH 3OH (g) is 1.6 x 10-8 at a certain temperature. If there are 1.17 moles of H 2 and 3.46 moles of CH3OH at equilibrium in a 5.60 L flask, how many moles of CO are present at equilibrium? 

Problem

The  equilibrium constant for the reaction 

                              2 H   2 (g)  +   CO (g) ⇌ CH 3OH (g) 

is 1.6 x 10-8 at a certain temperature. If there are 1.17 moles of H 2 and 3.46 moles of CH3OH at equilibrium in a 5.60 L flask, how many moles of CO are present at equilibrium?
