Entropy of the mixture increases

(C) When two different gases are mixed at constant temperature and pressure,the process is spontaneous and irreversible. Mixing leads to an increase in the randomness or disorder of the system. According to the second law of thermodynamics,for any spontaneous process,the entropy of the system increases. Therefore,the entropy of the mixture increases.
