In an effort to purify the output from a catalytic chemical reaction, C-Cl bonds are to be broken in a gaseous compound by means of LASER radiation. Determine the longest wavelength of radiation still capable of breaking the C-Cl bond. Express your answer in meters.
[Given: BEC-C = 334 kJ/mol; BECl-Cl = 243 kJ/mol]
-------------------------
tried so far:
E_C-Cl= Sqrt(334*243)+96.3(2.55-3.16)^2
E_C-Cl= 320.723 kJ/mol
E to break one bond
= (320.723*1000)/6.022*10^23
= 5.326*10^-19 J
E=hc/lambda
lambda = hc / e_single_bond
Lambda = 6.626*10^-34 * 299792458 / 5.326*10^-19
= 3.729*10^-7 m
but that number stinks for me,what do you think?
it's ok, that's 372 nm it's uv
I got same result
