As isolated box, equally partitioned contains two ideal gases A and B

1.	As isolated box, equally partitioned contains two ideal gases A and B as shown When the partition is removed, the gases mix. The changes in enthalpy (∆H) and entropy (∆S) in the process, respectively, are (A) zero, positive (B) zero, negative (C) positive, zero (D) negative, zero
Answer» Correct option (A) zero, positive Explanation: According to KTG Force of attraction and repulsion amongst molecules of ideal gas are negligible So, ∆H = 0 and randomness increases due to increase in volume so ∆S = +ve.

Answer»

Correct option (A) zero, positive

Explanation:

According to KTG

Force of attraction and repulsion amongst molecules of ideal gas are negligible

So, ∆H = 0

and randomness increases due to increase in volume so ∆S = +ve.
