درج ذیل میں سے کون سا بیان کیمیائی توازن کو ظاہر نہیں کرتا؟
A. Concentrations of reactants and products are constant
B. Forward and backward reactions occur at an equal rate
C. The system must be closed
D. Kc increases as the reaction progresses
Check answer and explanation
Answer: Kc increases as the reaction progresses
Explanation Chemical equilibrium is a state where forward and backward reactions occur at the same rate. At equilibrium , concentrations of reactants and products remain constant. It occurs in a closed system . The equilibrium constant (Kc) remains constant, not increasing . Therefore, Kc increasing is not a feature of equilibrium . Last verified on 11-04-2026
