ammonia enters a compressor at 1.128 bar and 335.13 k, and is compressed isothermally to 45.12 bar. following data are available for ammonia pc=112.8 bar, tc= 405.7, zc= 0.234 and w=0.253. assuming that the compression is done reversibly, calculate the heat and the work flow per mol of ammonia if a. nh3 beahaves as an ideal gas b. nh3 obeys the theory of corresponding states
