1. (25 points) 5 moles of liquid XXX (species 1 ) at 1 bar and 260K is mixed with 10 moles of liquid YYY (species 2) at 1 bar and 300K in a closed well insulated system to form a liquid mixture at 1 bar. We know the heat capacity of XXX and YYY to be 20R and 50R, respectively. We also have the following models for this mixture with A=1 and B=2 at the final temperature of the mixture. ln1=(A+3B)x24Bx22ln2=(A3B)x1+4Bx12H=(20x1+50x2+75x1x2)RT a. (20 points) Find the final temperature of the mixture. b. (5 points) Find GE/RT of this mixture at the final conditions
