PROII练习题：第1题：混合工质的性质是人们感兴趣的研究课题。试用PR状态方程计算由R12(CCl2F2)和R22(CHClF2)组成的等摩尔混合工质气体在400K和1.0，2.0，3.0，4.0和5.0MPa时的摩尔体积，组分的逸度系数，混合物的偏离焓和偏离熵。可认为该二元混合物的相互作用参数k12=0

第2题试用SRK、PR立方型状态方程关联与计算甲醇(1)-水(2）系在150℃下的汽液平衡。已知150℃甲醇(1)-水(2)系统的汽液平衡数据如下表所示ExperimentalCalculatedExperimentalCalculatedx1y1总压/MPay1总压/MPax1y1总压/MPay1总压/MPa0.0090.0600.50560.0610.50160.5780.7311.1070.7601.0910.0220.1350.54520.1300.53600.7480.8321.2230.8601.2110.0440.2130.59080.2220.58670.8930.9291.3350.9421.3120.0790.2860.64750.3180.65360.9130.9431.3410.9531.3240.1860.4590.79240.4790.78730.9360.9601.3550.9671.3420.3740.6100.96360.6310.94540.9530.9721.3630.9751.3520.4590.6621.0240.6861.0060.9690.9821.3740.9841.365
