(b) The following binary liquid phase reaction takes place at 100C inside a constant volume reactor, with van Laar's constants given below. Assuming the equilibrium concentrations at 100C to be CX=20kmol/m3 and CY=7kmol/m3, determine i. Equilibrium constant of the reaction at 100C. ii. Equilibrium constant of the reaction at 200C, with 1000J/mole heat of formation. iii. Change in Gibb's free energy (kJ/mol) for the reaction occurring at 200C. Reaction: 5X2Y Data for van Laar's constant at 100C:A=2.230;B=1.959
