Question

Which of the following is not a characteristics of equilibrium?

• A. Rate of forward reaction is equal to the rate of backward reaction at equilibrium
• B. Pressure, concentration, density remains constant at equilibrium
• C. Equilibrium can be obtained by either side of a reaction
• D. Equilibrium occurs only in open vessels at constant temperatures

Answer 1

The correct option is D Equilibrium occurs only in open vessels at constant temperatures

Equilibrium is attained for a reversible reaction when the rate of formation of products is equal to the rate of decomposition of products.

At a given temperature, pressure, concentration and density of the reaction at equilibrium is constant.

The equilibirum can be attained from either side. If the reaction is started with product, the reverse reaction will occur to reach the equilibrium and if the reaction is started with reactant, it will go forward to reach equilibrium.
Equilibrium reactions are always performed in closed container.
