Consider you are working at laboratory, and you have liquid n-hexane (C6H14) at ambient temperature and pressure (25°C and 1 atm). Based on your experiment procedure, you need to have vapor phase of n-hexane at 300°C and 1 atm. (a) Draw the hypothetical process path for phase change and calculate the enthalpy changes for each step. Determine the total specific enthalpy (kJ/mol) of n-hexane for this process. (b) Assuming ideal gas behavior, calculate the specific internal energy (kJ/mol) of the n- hexane vapor at 300°C and 1 atm

Question
Consider you are working at laboratory, and you have liquid n-hexane (C6H14) at
ambient temperature and pressure (25°C and 1 atm). Based on your experiment procedure, you
need to have vapor phase of n-hexane at 300°C and 1 atm.
(a) Draw the hypothetical process path for phase change and calculate the enthalpy changes
for each step. Determine the total specific enthalpy (kJ/mol) of n-hexane for this
process.
(b) Assuming ideal gas behavior, calculate the specific internal energy (kJ/mol) of the n-
hexane vapor at 300°C and 1 atm
