For the gas phase equilibrium \(2NO_2(g)\rightleftharpoons N_2O_4(g)\) in a sealed container at constant temperature, which statement is always true at equilibrium?

Select one option.

The concentrations of \(NO_2\) and \(N_2O_4\) are equal
The total pressure is the same as at the start of the reaction
The forward and reverse reaction rates are equal
The equilibrium constant must be 1
All macroscopic properties stop changing because molecular motion stops
