heat needs to be removed from the system. Calculate the heat transferred during this process, assuming that toluene behaves as a Redlich-Kwong fluid. Given T. =592 K, Pc = 41.3 bar, w =0.266, C, = 1.72 kJ (kg K)-1 and[9 marks] \left(\frac{\partial V}{\partial T}\right)_{P}=-\frac{\left(\frac{\partial P}{\partial T}\right)_{V}}{\left(\frac{\partial P}{\partial V}\right)_{T}} (b) For the Berthelot EOS, P(v-b)=A T-\frac{a(v-b)}{T v^{2}}, \text { with } a=\frac{27}{64} \frac{R^{2} T_{c}^{3}}{P_{c}} \text { and } b=\frac{1}{8} \frac{A T_{c}}{P_{c}} where v is the specific volume. Develop an expression for changes in specific entropy based on measurable properties (i.e., T, v and/or P) at isothermal conditions.[3 marks] (c) The excess Gibbs energy of a binary liquid mixture at constant temperature (T)and pressure (P) is given by: \frac{G^{E}}{R T}=\left(-2.6 x_{1}-1.8 x_{2}\right) x_{1} x_{2} Find expressions for In y1 and In 12 at T and P.
