Posted by Karen on Wednesday, November 7, 2007 at 3:53pm.

The bond energy of the O2 molecule is 495.

a) calculate the minimum frequency and max wavelength of light required to break this bond.
b) how many photons of this wavelength would it take in order to break open the bonds of all the oxygen molecules in a 384 mL container filled with oxygen at a pressure of 183.5 KPa and a temp of 36 degrees C? Assume 1 photon is used to break 1 oxygen bond.

i don't even know how to begin to solve this problem?!?!?!
