Question

A chemical reaction is said to have attained equilibrium when:

• A. equal amounts of reactants and products are formed
• B. reactants are completely converted to products
• C. the rate of forward reaction is equal to the rate of backward reaction
• D. the concentration of the reactants and products is the same

Answer 1

The correct option is C the rate of forward reaction is equal to the rate of backward reaction

When a chemical reaction is at equilibrium, the rate of forward reaction is equal to the rate of reverse reaction. Hence, the concentrations of reactants and products attain constant values known as equilibrium concentrations.
