Consider this equilibrium: n2(g) + 3h2(g) 2nh3(g) + energy. certain conditions provide less than 10% yield of nh3 at equilibrium. which statement describes this equilibrium? the keq is large and products are favored. the keq is small and products are favored. the keq is large and reactants are favored. the keq is small and reactants are favored. the conditions of the reaction must be known to answer the question.

The correct option is this: THE KEQ IS SMALL AND THE REACTANT ARE FAVOURED.
Since we are told in the question that the reaction give rise to only 10% product, this means that much product are not been produced, thus the reactants are favoured. Keq stands for the equilibrium constant of the reaction and it measures the rate at which the reactants are converted to products. For this reaction, the equilibrium constant is small and the backward reaction [reactant] is favoured.
