I really appreciate any help offered!

At 850°C, the equilibrium constant Kp for the reaction:

C(s) + CO2(g) --> 2CO(g)

has a value of 10.7. If the total pressure in the system at equilibrium is 1.000 atm, what is the partial pressure of carbon monoxide?

ANS - 0.921 atm

Thankyou!

First write down an expression for Kp.  This will give you an equation that relates the pressure of CO₂ to the pressure of CO.  To get a second equation relating the pressure of CO₂ to the pressure of CO, use the fact that the total pressure of the system is 1 atm.

haha thanks....who knew simultaneous equations would come in handy for chem down the track
