When two non-reacting ideal gases, A and B, in an isolated container initially separated by a partition are allowed to diffuse into each other by removing the partition, what are the values of \( \Delta H \) and the entropy change \( \Delta S \) of the system?

1. A
   \( \Delta H < 0 \) and \( \Delta S < 0 \)
2. B
   \( \Delta H = 0 \) and \( \Delta S > 0 \)
3. C
   \( \Delta H = 0 \) and \( \Delta S < 0 \)
4. D
   \( \Delta H > 0 \) and \( \Delta S = 0 \)
