Two kmol of CO2 dissociate to form an equilibrium mixture of CO2, CO, and O2 in which 1.4 kmol of CO2 is present. For a pressure of 5 atm, determine the temperature of the equilibrium mixture, in K.

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
