Calculate the entropy change of the universe

Reference no: EM131353245

Suppose that we have 1mol of a monatomic gas B₁, whose nuclei are in their lowest energy state, and 1mol of a monatomic gas B₂ consisting of exactly the same atoms as B₁, except that the nuclei are in an excited state whose energy ? is much larger than k_T and whose lifetime is much larger than the time for diffusion to occur. Both gases are at the same pressure and are maintained at the same temperature T by a heat reservoir.

(a) Immediately after the nuclei of gas B₂ have been excited, diffusion takes place. Calculate the entropy change of the universe.

(b) After the nuclei of gas B₂ have been excited, a time much larger than the lifetime of the excited state is allowed to elapse, and then diffusion takes place. Calculate the entropy change of the universe.
