The reference standard for all of our functions is 1 bar. This problem has you compute values at the old standard of 1 atm in order to assess the difference when producing new standard tables. Consider the vaporization of water at 25 degrees Celsius. Treat the vapor as ideal.

H2O(l) to H2O(g)

Thermodynamic Values at 1 bar standard.

H(l) = -285.83 kJ/mol H(g) = -241.82 kJ/mol

S(l) = 69.91 J/mol-K S(g) = 188.83 J/mol-K

a.)Calculate the equilibrium constant for this process and theequilibrium vapor pressureof water in torr.

b.)Calculate the enthalpy change upon changing the pressure from 1 bar to 1 atm.

c.)Calculate the entropy change upon changing the pressure from 1 bar to 1 atm.
