A mixture is composed of 70%CO2 and 30%CH4 (mole based). Determine the differences of specific internal energy, specific enthalpy and specific entropy for the mixture between T1=280K,v1=0,01m3/kg and T2=320K,v2=0,02m3/kg a) if the gases are assumed ideal. b) if the mixture is assumed ideal, and you use the Redlich-Kwong equation of state (Eq. 11.7 in the textbook) and the specific heat capacity for ideal gas, cp0(T), from Table A21 for each gas (as you did for CO2 in Exercise 10 Problem 1). c) if you use Redlich-Kwong with a=(iyiai1/2)2,b=iyibi (Eq.11.96) for the mixture and otherwise as in Problem b. When the specific volume is v0=10m3/kg, the pressure is so low that the gases for sure can be assumed ideal
