A vessel at 1000 K contains CO2with a pressure of 0.5 atm. Some of the CO2 is converted into CO on the addition of graphite. If the total pressure at equilibrium is 0.8 atm, the value of K is ???

vinitially        0.5    0             0
at eq'm     0.5-x    0           2x
As solids do not contribute to pressure.
Given total pressure= 0.5-x+2x=0.8
x=0.3
Thus 
pco2 = 0.5-0.3 = 0.2 atm 
pco = 2*0.3 = 0.6 atm 

So eq'm constant will be: kp = 1.8
