(2) decreasing

(3) constant

(4) zero

Verified Answer :

i think the reason why the reaction is at equilibrium after 60 seconds is because the concentration of both NO2 and N2O4 are : Constant, which means that they do not undergone any change

hope this helps

Answer: The correct answer is Option 3.

Explanation:

Chemical equilibrium is defined as the point where the concentrations of reactants and the products do not change with time.

The equation for the equilibrium between \(NO_2\text{ and }N_2O_4\) follows:

\(N_2O_4\rightleftharpoons NO_2\)

Initially, the concentration of the reactants decrease and the concentration of the products increase as seen from the graph. But after 60 seconds, the concentration of both reactants and products do not change and hence equilibrium is attained.

Hence, the correct answer is Option 3.
