It takes 242./kJmol to break a chlorine-chlorine single bond. Calculate the maximum wavelength of light for which a chlorine-chlorine single bond could be broken by absorbing a single photon. Round your answer to 3 significant digits.

The working equation for this is the Planck's Law:

E = hc/λ

where

E is the energy

h is the Planck's constant equal to 6.62607004*10⁻³⁴ m²· kg / s

c is the speed of light equal to 3 * 10⁸ m/s

λ is the wavelength

Assuming 1 mol of Cl-Cl bond,

242 kJ * 1000 J/1 kJ = (6.62607004*10⁻³⁴ m²·kg / s) (3*10⁸ m/s) / λ

λ = 8.214*10⁻³¹ m
