Self-Test 9.9B

Calculate the standard entropy of vaporization of benzene, C6H6, at 276.0 K, given that the molar heat capacity at constant pressure of benzene vapor is 82.4 J K 1 mol 1 in this range (see Tables 8.2 and 8.3). I understand step 2 and step 3 in the solution but i don't understand step 1. How do you g...

Re: Work function

I understand what you're saying and you are correct because since you have a longer wavelength you have less energy. And if E(photon)<(work function the electron) then the electron will not eject.
