The question is incomplete, the complete question is;
It takes 412. KJ/mol to break a carbon-hydrogen single bond. Calculate the maximum wavelength of light for which a carbon-hydrogen single bond could be broken by absorbing a single photon. Round your answer to significant digits.
Answer:
289 nm
Explanation:
The energy of the photon = 412 × 10^3/6.02 × 10^23 = 6.84 × 10^-19 J
From;
E = hc/λ
h= Plank's constant
c= speed of light
λ = wavelength
λ = hc/E
λ = 6.6 × 10^-34 × 3 × 10^8/6.84 × 10^-19
λ = 2.89 × 10^-7 m
λ = 289 nm
