I Review | Constants | Periodic Table
The iodine molecule can be photodissociated (broken
apart with light) into iodine atoms in the gas phase
with light of wavelengths shorter than about 792 nm
A 110.0 ml. glass tube contains 42.6 mtorr of
gaseous iodine at 15.0 °C.
Part A
What minimum amount of light energy must be absorbed by the iodine in the tube to dissociate 16.0 % of the molecules?
Express your answer with the appropriate units.

Expert Solution
Step 1

Given that :

The wavelength of light=792 nmVolume of glass tube=110.0 mLPressure of iodine=42.6 mTorrTemperature=15°C

We have to calculate the amount of light energy absorbed by the iodine to dissociate 16.0 % of the molecules.
