### Re: Heat Capacities

To calculate the molar heat capacities I believe that we just have to memorize that you multiply the gas constant by 5/2 for constant volume and then multiply the gas constant by 7/2 for constant pressure.

### reversible vs irreversible work

I am a little confused on how you can tell whether a system is reversible or not?

### Re: pressure

The partial pressure is the pressure of an individual gas in a mixture while the total pressure is the sum of the partial pressures.
