Equilibrium pressure.. Where am I going wrong?
« on: October 01, 2008, 08:50:13 PM »
Consider the following reaction, equilibrium concentrations, and equilibrium constant oat a particular temperature. Determine the equilibrium pressure of CO.

CO(g) + 2 H2(g) <---> CH3OH(l)           Kp = 2.25 x 10^4
                                                      P(H2)eq= 0.52 atm

This is my work:

2.25 x 10^4 = (CO) * (.52)^2

(CO) = 8.3 X 10^4

For some reason, the answer on my practice quiz is 1.6 x10^4 atm. I know that liquids aren't present in the equation, but I don't understand why my answer is wrong.

Write out the formula for the equilibrium.
Where are you putting the CO and H2?
