An isolated box, equally partitioned contains two ideal gases A and B as shownWhen 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» Answer is : (a) zero, positive ∆H for this process = CV∆T = 0 (at constant temperature) ∆S for this process will be positive that is ∆S > 0, the randomness increases the molecules of gases A and B gets intermixed with each other, when the partition is removed. |
