Problem 3 (10%)(a) (8) A vessel, divided into two parts by a partition, contains 4 mol of Agas at 350K and 30 bar on one side and 3 mol of B gas at 350K and 20 baron the other. If the partition is removed and the gases mix completely toform a gas mixture also at 350K, what are the changes in enthalpy, entropyand Gibbs free energy? Assume both A and B gases are ideal gases withCv = 2.5R. R =

(b) (2) The enthalpy of a C-D binarysystem at fixed T and P is represented by the equation: H = 600xc +  400xD+xcxD(40xc+20xD). Is this binary system an ideal solution?Why or why not?
