InterviewSolution

1.	A rubber balloon permeable to hydrogen in all its isotopic forms is filled with deuterium (D_(2)) and then placed in a box containing pure hydrogen. Will the balloon expnad or contract or remains as it is ?
Answer» SOLUTION :Since the MOLECULAR weight of `D_(2)` is greater than that of `H_(2)`, rate of diffusion of `H_(2)` will be HIGHER than that of `D_(2)`. Thus, the balloon will expand.
