Question

The strength of common bonds in living organisms range from 300 to 500 kJ/mol. For example, single carbon-carbon bonds in a organic molecules have energies of about 348 kJ/mol (that is, the energy required to break a single carbon-carbon bond is 348 kJ/mol). Calculate the minimum wavelength of light needed to break the C-C bond. Could UV lamps be used to break the C-C bond?

Answer 2

I think we will need to use this equation:
\[E=\frac{ hc }{ lambda }\]

Answer 3

So I'm solving for lamba then? so it's hc/E?

Answer 4

Yep

Answer 5

For this one, I need DeltaE right? So its' 500 kj/mol - 300 kj/mol so hc/200 kj/mol?
