I need to solve part b, c, d, e also

Example 13.1 For the system methanol(1)/methyl acetate(2), the following equations provide a rea- sonable correlation for the activity coefficients: I In Y1 = Ax? In y2 = Ax where A= 2.771 0.00523T In addition, the following Antoine equations provide vapor pressures: 3643.31 2665.54 In Pat = 16.59158 - In Psat = 14.25326 - T - 33.424 T - 53.424 where T is in kelvins and the vapor pressures are in kPa. Assuming the validity of Eq. (13.19), calculate: (a) P and {yi) for T = 318.15 K and x1 = 0.25. (b) P and {i} for T = 318.15 K and y1 = 0.60. = (c) T and {yi} for P = 101.33 kPa and X1 = 0.85. (d) T and (xi) for P= 101.33 kPa and Y1 = 0.40. (e) The azeotropic pressure and the azeotropic composition for T= 318.15 K
