4. For the autoionization of water: 2 H2O(l) <=> H30+(aq) + OH*(aq) the equilibrium constant Kw is 1. 139 x 10-15 at 273.15 K and 9.614 x 10-14 at 333.15 K. Assume that AH° and ASº for this process are independent of temperature from 273 to 333 K. a) Determine AH° and ASº for the autoionization process. b) If the pH of pure water were 7.000 this would imply that Kw...

This is a question for homework in an undergraduate Physical
Chemistry class:
- Please use 273.15 when
converting between Kelvin and Celsius temperatures.
- Use 96485 for Faraday Constant
- In problems that require fitting of a curve or straight line
use linear regression. Do not use trend line. Sometimes the results
can be different.

Please show all work and explanations! Calculate ΔE, ΔS, ΔG, Q and W for the vaporization of 3.00 moles of liquid water to form water vapor at 100°C and 1.00 atm pressure. The standard molar enthalpy of vaporization of water is 40.67 kJ/mol. The density of liquid water at 100°C is 0.958 g/cm3 . Assume that the water vapor is an ideal gas, but be careful – the initial state is liquid water, so this is not simply an ideal...
