JEE Main 2025 Apr 3 Shift 1, Chemistry Q10: Gibbs Energy Change and Equilibrium

JEE Main2025Apr 3, Shift 1Chemistry
Q.

Which of the following properties will change when system containing solution 1 will become solution 2 ?

  1. A

    Molar heat capacity

  2. B

    Density

  3. C

    Concentration

  4. D

    Gibbs free energy

Solution

Both solutions have the same composition (1 mol of solute per 1 L of water), so all intensive properties — concentration, density, molar heat capacity, chemical potential — are identical.

Gibbs free energy is an extensive property, scaling with the amount of substance. Since solution 1 contains ten times the material of solution 2, its total is different.

Only the Gibbs free energy changes.
