Answer:
This indicates that the equilibrium constant for this reaction at this temperature is less than 1.0 (< 1.0).
Explanation:
When the equilibrium constant (K):
K < 1 → [reactants] > [products].
K = 1 → [reactants] = [products].
K > 1 → [reactants] < [products].
Since the reaction is colorless (color of N₂O₄), it is shifted towards the reactants which means that [reactants] > [products].
So, K < 1.
