3. In older literature x and y data for binary VLE are sometimes represented by smoothing equations of the form: 1 +a x 2 + bix z a 12 1 +a, x, + bzx , where a , is the relative volatility and the a's and b's are empirical constants. For the carbon disulfide(1)-acetone(2) system at 35.17 C, the following values of the constants are reported: a = 7.1875 b1 = -2.4064 a2 = 1.4685 b2 =2.5891 At 35.17 C, the vapor pressures of the pure species are 69.8 kPa and 46.9 kPa for components 1 and 2 respectively. Using only the data given here, determine good estimates for the infinite dilution activity coefficients, y, and y2, and the azeotropec composition
