D) A gas obeys the EOS: v=PR0TRoTk In a constant enthalpy process, the initial state of the gas at pressure, P1=50 bars and temperature, T1=300K was changed to a final state at pressure, P2=2 bars and temperature, T2. i) Use the appropriate general equation and the given EOS, calculate (showing the steps) the value of the Joule-Thomson coefficient () of the gas [7 marks] ii) Calculate the steady-state final temperature (T2) of the gas in the process [4 marks] Data: k (constant) =11.0kJm3/kmol;CP=29.0kJ//mol;;R0=8.314k/kmolK
