Question

9. For a chemical system that is in dynamic equilibrium, which of the following statements is FALSE? A) Both reactants and products are present in the reaction mixture B) The C) The reactan is changed composition of the reaction mixture does not change with time equilibrium constant describing the mass ratio of products to ts in the chemical system does not change unless the temperature of conversion to products is the same as the rate of conversion ) The to reactants rate the forward and the backward reactions are occurring, but each have different rates

Explanation / Answer

The false statement is BOTH THE FORWARD and BACKWARD REACTIONS ARE OCCURING, BUT EACH HAVE DIFFERENT RATES.

Since, if any chemical system is at dynamic equilibrium, the rate of forward reaction is equal to the rate of backward reaction.

Therefore the anwean is option E
