enthalpy constants?

Postby Mallika Singh 1G » Sun Mar 15, 2020 7:43 am

what exactly was the purpose of the 3/2R and 5/2R constants? when would we need to use them?

For a detailed description and related exercises, check p.264 in the textbook and 4C exercises.

It's for ideal gases, and if they're monatomic, diatomic, and so on. For Chem 14B we are only concerned about monatomic and diatomic ideal gases.

Which one, 3/2R or 5/2R, corresponds with constant volume and which corresponds with constant pressure?

I believe they pertained to kinetic energy.

I think that those constants are used for ideal gases.

These are constants that we can use when looking at ideal gases. I think we can use them when we don't know the Cv and Cp but we do know that the gas is ideal (monoatomic/diatomic).
