22. Determine ΔS, ΔU, ΔH, ΔA, ΔG when mixing VA m3 of gas A and VB m3 of gas B; T=298 K. The initial pressure of the gases is 1.01*105 Pa. The final volume of the mixture is VK= VA VB. Gases A and B and their volumes are given in the table on p.95 (assume that these substances obey the laws of ideal gases).
Option N Gas A VA*104, m3 TA,K Gas B VB*104, m3 TB,K P, Pa
