Unformatted text preview: H since E = (H- P V) = H- P V. V = the change in molar volume of the system. Assuming that C 2 H 6 and O 2 are ideal gases and the molar volume of gas >> the molar volume of liquid. Based on your calculation, what are the relative contributions of H and P V to E ? T P T dT C H H 298 . r H is known but C P is unknown. At 500 C, ethanol will become vapor. Thus, the total change of enthalpy is H t = H T + trs H, where trs H is the enthalpy change for phase change which is also unknown. 3.13. ) atm ( G ) atm ( G ) atm ( G ) atm ( G A C B 100 100 100 100 where A = CH 3 COCOOH (l), B = CH 3 CHO (g), and C = CO 2 (g) For isothermal process, determine the pressure dependence of G for liquid and ideal gases separately based on the equations discussed in the class. Is the pressure dependence of G negligible?...
