### 2016 Midterm Question 8C

Why doesn't altering the size of the electrode affect the potential of a cell? Because I thought that the electrode grew in size as the current flowed into the products side.

### Re: Enthalpy of Vaporization of Water

I believe that the deltaHvap value of 40.7 kJ mol^-1 refers to the standard enthalpy of vaporization of water at its normal boiling point, 100 degrees Celsius. Therefore, the other deltaHvap value of 44.0 kJ mol^-1 refers to the standard enthalpy of vaporization of water at its standard room tempera...
