Hi everyone

Well, I have a problem with my final project in high school. I’m writing in chemistry and physic, and it is about neutron activation and photochemical activation, among other things. But now I have asked both my teachers and they cannot help me. So hire it is:

Neutron activation (in a neutron source):

I know that I start with a filled solution of “kaliumpermanganat” KMnO4. And it has to me made into MnO2. And I also know that Mn2+ becomes beta active during the process:

MnO4- + neutron -> MnO2

Photochemical activation:

I use the same material KMnO4 and the same thing happens, though this is a very slow reaction, we are talking days… Well I think it have something to do with bindings energies

MnO4- + light -> MnO2

So if any of you have any idea what happens in these to reactions, I would be delighted…
