part ii and b please

Antoine coefficients ( P in mmHg,T in K, log to base e ): Methanol: A=18.588,B=3626.6,C=34.29 Water: A=18.304,B=3816.4,C=46.13 Ethanol: A=18.9119,B=3803.98,C=41.68 Margules parameters: Methanol-Water: Amm=0.6174,Amw=0.7279 Ethanol-Water: Aw=0.7917,Aww=1.6366 1. a) Calculate the Henry's Law constant for dilute methanol in water at 1 atmosphere: i) assuming ideal solution behaviour; ii) using the Margules Coefficients provided to account for the non-ideality of the solution. Compare your answers with the value roughly obtained from the gradient in the xy diagram below. b) Now repeat part a) but this time to determine the Henry's Law constant for dilute water in methanol at p=1atm. Again, compare your results to the constant roughly obtained from the xy diagram
