Question
The energy required to break one mole of Cl-Cl bonds in Cl2 is 242 kJ mol-1. The longest wavelength of light capable of breaking a single Cl - Cl bond is
(c = 3 × 108 ms-1 and NA = 6.02 × 1023 mol-1)
(c = 3 × 108 ms-1 and NA = 6.02 × 1023 mol-1)
Options
A.594 nm
B.640 nm
C.700 nm
D.494 nm
Solution
Energy required for 1 Cl2 molecule = 
Joules
This energy is contained in photon of wavelength ′λ′
= 4947
= 494 nm
