IIT/JEE Chemistry Practice #23: Graham's Law of Effusion

Dave explains a problem involving Graham's Law of Effusion, focusing on the equilibrium between diatomic chlorine and chlorine radicals. The video explores how to determine the fraction of chlorine molecules dissociated into radicals by measuring the rate of effusion compared to krypton. Using Graham's Law and equilibrium calculations, the video demonstrates how to solve for the average molar mass of the mixture and determine the proportion of dissociated chlorine molecules.

What is the molar mass of Krypton, and how does it relate to the molar mass of the mixture?

Explain how the initial concentration of chlorine affects the equilibrium concentration of chlorine radicals.

What calculations are necessary to find the proportion of chlorine molecules that dissociate?
