A rigid container is divided into two compartments of equal volume by a partition. The temperature of gases in both compartments is the same(298 K) and is not changed during the mixing of the gases Calculate the increase in entropy which occurs when the partition between the two compartments is removed. a) If both compartment contains I mole of ideal gas A. Answer b) If one compartment contains 1 mole of ideal gas A, and the other contains I mole of ideal gas Answer c) If the first compartment had contained 2 moles of ideal gas A, and the other contains ! mole of same ideal gas, Answer d) If one compartment contains I mole of ideal gas A, and the other contains 2 mole of ideal gas B
