Respuesta :
Answer: Option (C) is the correct answer.
Explanation:
A reaction in which rate of forward reaction equals the rate of backward reaction then this type of reaction are known as equilibrium reaction.
They are reversible in nature. Also, equilibrium reactions occur only in closed containers because otherwise there is possibility that a reactant might escape from the system and hence a change will occur in the rate of forward and backward reaction.
Therefore, we can conclude that out of the given options, the statement reactions go to completion is not a characteristic of chemical equilibrium.
