Assume that the ?Ho and ?So of vaporization do not change significantly with temperature. Calculate the vapor pressure of CH3OH at 70 oC (in atm). CH3OH (l) ? CH3OH(g)?Ho = 38.0 kJ and ?So = 112.9 J/K (Don't round unil the end. Using the exponent enlarges any round-off error.)
Changing the conditions of the reaction can alter the value of the change in free energy (?G). Sort the following conditions as to whether each would decrease the value of ?
