explain chemical equilibrium is dynamic in nature
Answers
Answer:
“Equilibrium is the state at which the concentration of reactants and products do not change with time. i.e. concentrations of reactants and products become constant.”
The important characteristics of equilibrium state are,
(1) Equilibrium state can be recognised by the constancy of certain measurable properties such as pressure, density, colour, concentration etc. by changing these conditions of the system, we can control the extent to which a reaction proceeds.
(2) Equilibrium state can only be achieved in close vessel.
(3) Equilibrium state is reversible in nature.
(4) Equilibrium state is also dynamic in nature.
(5) At equilibrium state,
Rate of forward reaction = Rate of backward reaction
(6) At equilibrium state, ΔG = 0, so that ΔH = TDS.
Answer:
At chemical equilibrium state, the rates of the forward and the backward reactions are equal and the concentrations of the reactants and the products reach constant values. At chemical equilibrium the reaction still continues to take place in both the directions with the same rates. The reactants continue to form the products while the products also continue to form the.reactants. Because of such a situation at the equilibrium state in the reaction system, the chemical equilibrium is called a dynamic equilibrium
