Question

What is equilibrium and its condition?

Answer 1

1. Chemical equilibrium is set up when there is no change found in the reactant as well as in the product.
2. In an equilibrium system rate of forward reaction is equal to the rate of backward reaction and no specific change in concentration is observed.
3. Chemical equilibrium is the stage where no more reactants produce products but at the same time the reaction continues with no relative change can be observed in the rate of the reaction.
4. There may be certain conditions that need to be fulfilled to attain stable equilibrium is as follows:

• The system must be isolated, no transfer of heat or mass occurs.
• The rate of forward and backward reactions is equal.
• The number of reactants must be equal to the product even after equilibrium is achieved.
• Pressure and temperature should be properly maintained in overall reaction rates.
