Question

if the equilibrium - constant for a reaction is 1, what can be inferred about the system at equilibrium? the system favors the formation of products the system favors the formation of reactants the concentrations of reactants and products are equal the reaction does not occur

Explanation:

The equilibrium constant ($K$) is defined as the ratio of the concentration of products to the concentration of reactants at equilibrium. When $K = 1$, the ratio of product - to - reactant concentrations is 1, meaning the concentrations of reactants and products are equal at equilibrium.

Answer:

The concentrations of reactants and products are equal
