Please write neatly and provide explainations . Thank you!!! Will give a upvote!!!

A number of different experimental methods have been used to determine molecular diffusivity for gas phase system. Propose and describe a suitable experimental method to determine the diffusion coefficient of pure Carbon dioxide, CO2 gas for a system that has equal pressures of CO2 and Nitrogen, N2. Your experimental method should include the name of the proposed method, the description of experimental apparatus (including apparatus sketch), brief procedure/methodology, and related equations involved in diffusivity determination
