Question

Given the reaction at equilibrium:

CO32–(aq) + H2O(l) HCO3–(aq) + OH (aq)

Which statement is always true?


A)
[CO32–] is less than [OH–].

B)
[CO32–] is less than [HCO3–].

C)
The rate of the forward reaction is less than the rate of the reverse reaction.

D)
The rate of the forward reaction equals the rate of the reverse reaction.

Answer 1

Answer:

4

Explanation:

Equilibrium is a dynamic state in which the forward and reverse reaction rates are equal; the quantities of the reactants and products are not necessarily equal.

(You got this keep up the good work). :)

Answer 2

The rate of the forward reaction equals the rate of the reverse reaction in the equilibrium reaction.

What is equilibrium?

A state of balance between opposing forces or actions.

Equilibrium is when the rate of the forward reaction equals the rate of the reverse reaction.

All reactant and product concentrations are constant at equilibrium.

Equilibrium is a dynamic state in which the forward and reverse reaction rates are equal; the quantities of the reactants and products are not necessarily equal.

Hence, option D is correct.
