Question

It has been found that gaseous iodine molecule
just dissociates into iodine atoms after absorption
of light at wavelengths 4995 Å. The energy required
to dissociate 1 mole of iodine molecules is
(1) 52.2 K cal/mole (2). 93.4 K cal/mole
(3) 63.4 K cal/mole (4) 57.3 K cal/mole​

Answer 1

Answer:

(4)

Explanation:

conversions I used here are...

hc = 12400eV-A°

1eV = 1.6 x 10^(-19) J

to convert Joule into Calorie....divide by 4.2
