Which outcome changes the Van't Hoff constant values?

A)Introducing a common ion species
B)Lowering the solvent dielectric constant
C)Increasing electrolyte solution temperature
D)Adding a non-reactive indicator dye

💡 Explanation

Increasing temperature affects the equilibrium constant because Van't Hoff explicitly relates the equilibrium constant's temperature dependence to enthalpy change via the Gibbs-Helmholtz equation. Therefore, temperature changes the constant; rather than altering ion concentrations or solvent properties under constant conditions.
