please post step by step solution

Consider a stream consisting of a mixture of acetone and methanol. The stream is to be used as the solvent in a liquid phase reaction operating at low pressure (1.1 bar absolute and lower). In order to design the reactor you need to describe the phase equilibria of this stream. 2.1 If the stream contains 76 mole % acetone (1) and 24 mole % methanol (2) what is the dew point pressure in kPa at 55C as predicted by Raoult's Law?. 2.2 Freshwater and Pike (J. Chem. Eng. Data vol 12p179183,1967 ) give the dew point pressure of a 76 mole % acetone and 24 mole % methanol mixture at 55C as 100.5kPa. Comment on the ideality of the mixture and, if non-ideal, indicate what type of deviations are present and justify your answer. 2.3 The Gibbs free energy expression of the Gibbs-Duhem equation is used in the derivation of the thermodynamic consistency test. This test is very important in detecting incorrect or nonthermodynamically consistent data. If G=f(T,P,n1,n2) prove the Gibbs-Duhem expression for Gibbs free energy: x1dG1+x2dG2(T(G))P,x1,x2dT(P(G))T,x1,x2dP=0
