For any reversible reaction, if we increase concentration of the reactants, then effect on equilibrium constant
- depends on amount of concentration
- unchanged
- decrease
- increase
Answer
(2) unchanged
Solution
As per NCERT, the equilibrium constant of a reaction has a fixed value at a given temperature; it changes only with temperature.
On increasing the concentration of reactants, the reaction quotient Q becomes less than K, so the equilibrium shifts in the forward direction until Q again equals K.
∴ The equilibrium constant remains unchanged.
