Please help me to solve this problem.

2. The following apparatus is employed to de termine the poolecular diffusivity for binary gas mixture. The apparatus consists of two glass bulbs with volume Vi and Va connected by a capillary of cross-sectional area A and length L whose volume is small compared to li and 12. Pure gas A is added to Vi and pure gas B to V2 at the same pressure. The value is opened , diffusion proceeds for a given time, and the value equation for measuring the diffusivity, ie C2 = f ( DAR I Can IV, VL. A. t) where Car is the average cancen tration at equilibrium ord t is time (25%) (Hint: Need to perform a material balance within the control volume of V2) Gas B Gas A V. Valve Vi A Cz C CA L 0
