Question

Mixing of two different ideal gases under istohermal reversible condition will lead to

• A. inccrease of Gibbs free energy of the system
• B. no change of entropy of the system
• C. increase of entropy of the system
• D. increase of enthalpy of the system

Answer 1

Answer: (C)

On mixing of two different ideal gases under| isothermal reversible conditions, $\Delta S_{\mathrm{mix}}$ is always positive $i.e_{.}$, increasing.
