Write short notes on pool boiling of saturated liquid with neat sketch of flux vs temperature drop?

Derive the equation for the partial pressure distribution of A and B for diffusion of A through non-diffusion B considering the point z-0 to z-z where the partial pressure of A is PA?

A Test tube, 1.5 Cm in diameter and 12cm long, has 0.4g camphor on it. How long will it take for the camphor (C,H,O) does disappear? The pressure is atmospheric and the temperature is 200C. The sublimation pressure of camphor at this temperature is 97.5 mmHg and the diffusivity of camphor can be estimated by using the fuller' equation. Diffusion volumes: C-16.4, H=1.98, O-5.48, Air 20.1?

Explain the two methods with neat diagram how to predict or measure the gas-phase diffusion coefficient?
