Given the equation representing a closed system:N2O4(g) <=> 2NO2(g)
Which statement describes this system at equilibrium?
(1) The volume of the NO2(g) is greater than the volume of the N2O4(g)
(2) The volume of the NO2(g) is less than the volume of the N2O4(g)
(3) The rate of the forward reaction and the rate of the reverse reaction are equal
(4) The rate of the forward reaction and the rate of the reverse reaction are unequal

3., the equation is balanced so the forward and reverse reactions are equal

Answer: The correct option is (3).

Explanation:

[tex]N_2O_4(g)\rightleftharpoons 2NO_2(g)[/tex]

An equilibrium in a reversible chemical reaction is a state in which concentration of reactants and products do not change with time. At equilibrium the rate of forward reaction is equal to the rate of backward reaction.

So, from the given statements the correct statement describing the given system at equilibrium is statement numbered '3'
