Question

Given the reaction N₂O₄(g) ⇌ 2NO₂(g), what shifts will occur if Q = K?

a) The reaction shifts to the left.
b) The reaction shifts to the right.
c) No shift as the reaction is in equilibrium.
d) No shift because the product is 2NO₂.

Answer 1

If Q equals K for the reaction N₂O₄(g) ⇌ 2NO₂(g), this means the reaction is at equilibrium and no shift will occur in either direction.

Step-by-step explanation:

When considering the reaction N₂O₄(g) ⇌ 2NO₂(g), and it is stated that Q = K, this means that the reaction quotient (Q) is equal to the equilibrium constant (K). This indicates that the reaction is in equilibrium and no shift in the direction of the reaction will occur, neither to the left nor to the right. Therefore, the correct answer is c) No shift as the reaction is in equilibrium.

In this reaction, N2O4(g) ⇌ 2NO2(g), if Q = K, it means that the reactant and product concentrations are already at equilibrium and there is no need for a shift in the reaction. Therefore, the correct answer is c) No shift as the reaction is in equilibrium.
