+//(14.3)  Measurements show that at a temperature T and a pressure of 1 atm, the equilibrium mixture for the system of Example 14.2 has the composition yCO = 0.298,yO2 = .149, yCO2 = .553.Determine the temperature T of the mixture, in K.

+
+//solution
+yCO = .298
+//solving yCO = 2z/(2 + z)
+z = 2*yCO/(2 - yCO)
