Consider the reaction below, where K = 170 at 298 K. 

At a certain time, 0.015 M NO₂(g) and 0.025 M N₂O₄(aq) are present.

Determine if the reaction is at equilibrium or not. If not, explain briefly which way must the reaction proceed to reach equilibrium.

Beskou die reaksie hieronder, waar K = 170 by 298 K.

Op 'n sekere tyd is 0.015 M NO₂(g) en 0.025 M N₂O₄(aq) teenwoordig.

Bepaal of die reaksie by ewewig is of nie. Indien nie, verduidelik kortliks na watter kant moet die reaksie voortgaan om ewewig te bereik.
