Ethanol vapor at 05 bar and 78 degrees celcius is, Ask an Expert

Academics

Ethanol vapor at 0.5 bar and 78 degrees celcius is compressed isothermally to 2 bar in a reversible process in a closed system a) draw a qualitative PV graph and show the path of the process. Mark all the relevant pressures and isotherms b)Calculate the enthalpy change of the ethanol c) calculate the entropy change of the ethanol d) what amount of heat is exchanged between the ethanol and the surroundings during the compression? Assume that ethanol vapor is an ideal gas with Cp=45J/Kmol. The saturation pressure of ethanol at 78 degrees celcius is 1bar.
