Answer:
The equilibrium constant tells us how much the reactants and products are present in an equilibrium system. If a factor causes the value of the equilibrium constant to decrease, it means that the concentration of the reactants will increase compared to the products. In this case, the factor that would cause the equilibrium constant to decrease for the reaction N₂OH(g) Heat (2 No ₂(g) would be an increase in temperature. When the temperature increases, the reaction favors the endothermic direction, which means more reactants will be formed and fewer products. As a result, the equilibrium constant decreases.
