Question

A chemical reaction A⇌B is said to be at equilibrium when:

• A. Complete conversion of A to B has taken place
• B. Conversion of A To B is only 50% complete
• C. Only 10% conversion of A to B has taken place
• D. The rate of transformation of A & B is just equal to the rate of transformation of B To A in the system

Answer 1

The correct option is D The rate of transformation of A & B is just equal to the rate of transformation of B To A in the system

A chemical equilibrium is the state when concentration of reactants and products do not change with time. It is attained when rate of forward reaction becomes equal to rate of backward reaction.
