Solution

            CO2(g) + C(s) -----------> 2CO(g)
   I        1.33                                    3.95
   C        +x                          -2x
   E       1.33+x                        3.95-2x

          Kp   = P^2CO/PCO2
          1.5 = (3.95-2x)^2/1.33+x
          1.5*(1.33+x) = (3.95-2x)^2
             x = 1.03
     PCO2 = 1.33+x   = 1.33+1.03 = 2.36atm
     PCO   = 3.95-2x = 3.95-2*1.03 = 1.89atm
