Redlich-Kwong (RK) model is popularly used for equation of state and is described by RT a P= - b ( +b) where R?72 a = 0.42748 a, , b= 0.08664 (22) and a - (1. = 1) P For asymmetric molecules, the accuracy is improved by Redlich-Kwong-Soave (RKS) model which is the same as RK except that = 1 =[ + m{ 1 T,"s) 1-1,05)}, where m = 0.480 +1.5740 0.176@ and @ is the Pitzer acentric factor. We want to quantify the error of RK in the molar volume of methanol at T = 300 C(= 573.15 K) assuming that RKS represents reliable physical properties. Namely, the relative error is defined as RKS - RK RK EE RKS The thermodynamic properties of methanol at the critical point are T. = 512.6 K , P. = 79.9 atm , a and V = 0.1761/mol. The Pitzer acentric factor of methanol is o = 0.559. Develop a function file HW6_YourLastName.m that calculates and plots the error (y-axis) as a function of pressure P(x-axis). The function file should be executable as a stand-alone file. In the graph, the range of the pressure is 20 atm s P T, and P
