Work Function

Postby Clara Cho 2K » Tue Nov 05, 2019 10:33 pm

If I'm given the work function in kJ.mol^-1, do I have to convert it to Joules per electron to use it in my calculations for energy of a photon?

yes just convert KJ/mol to either J/mol or J/electron.. usually the question will specify if you need it per electron but I believe it's generally J/mol.

A lot of the practice questions convert it to J/mol so that's probably your best bet. Just make sure your units cancel out while you're doing the equations and you should be fine.

If I'm solving for the energy of a photon, would I use J/mol or J/electron?

J/mol of photon
