One mole of krypton, argon and neon each is stored side by side at 300K and 1atm: Kr Ar Ne (a) How much will the entropy of this system increase if the barriers are removed and those three gases are allowed to mix freely? Give answer to 2% accuracy. W (b) What if we instead replaced the krypton with argon, then removed the barriers and allowed the gases to mix freely? What is the increase in the system's entropy in this case? (Think: should this be more or less than the answer to part (a))? Give answer to 2% accuracy. In lecture, we derived that the entropy of an ideal gas is given by where the textbook states that for a monatomic gas. Compute the entropy of1 mole of (a}Argon 154]? J/K (b) Neon 146.26 JKK (c) Krypton 164 .lfK at 300 K and at atmospheric pressure. Give answer to 2% accuracy
