The water-gas shift reaction plays a central role in the chemical methods for obtaining cleaner fuels from coal: co(g) + h2o (g) ⇋ co2(g) + h2(g) at a given temperature, kp= 2.7. if 0.10 mol of co and h2o, and 0.20 mol of h2 and co2 are put in a 2.0 l flask, is the mixture at equilibrium, if not which direction will it shift?

The reaction is not in equilibrium and moves to the left until Q equals Kc.

Explanation:

Hello!

First we must check that the equation is balanced.  

We propose the constant Kc for the balanced equation.  

We propose Q for the balanced equation.  

We calculate the value of Q and compare with Kc

If Q = Kc the reaction is in equilibrium.

If Q> Kc the reaction moves from right to left.

If Q <Kc the reaction shifts from left to right.  

We obtain the value of Kc from the value of Kp. If the variation of mol is zero Kp = Kc
