  • question_answer 62)   Given that \[\Delta H=0\] for mixing of two gases. Explain whether the diffusion of these gases into each other in a closed container is spontaneous or not?

    Answer:

      \[\Delta G=\Delta H-T\Delta S\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,......(i)\] \[\Delta H=0\]and\[\Delta S=+ve\]for mixing of two gases hence \[\Delta G\] will be negative and the process of mixing will be spontaneous.
