Acetic acid and water react to form hydronium cation and acetate anion, like this: HCH3CO2(aq) + H2O(l) → H3O^+ (aq) + CH3CO2^-(aq)

Imagine 226. mmol of CH3CO2- are added to a flask containing a mixture of HCH3CO2, H2O, H3O and CH3CO2- at equilibrium, and then answer the following question.

What is the rate of the reverse reaction before any CH3CO2^- has been added to the flask?

The answer is "Greater than zero, and greater than the rate of the reverse reaction".

Explanation:

It applies a rate of reaction to the balance, a forward response dominates until it reaches a constant. This process is balanced before 52 mmol of the reactant, to which 3 is added. In balance, that rate of the forward reaction was its rate with forwarding reaction, both of which are higher than 0 as the response has achieved balance so that both species get a level greater than 0.
