Solved Using values of delta Gf, calculate delta Grxn for - Chegg The ratio of products to reactants is less than that for the system at equilibriumthe concentration or the pressure of the reactants is greater than the concentration or pressure of the products. Because \(Q\) < K, the reaction is not at equilibrium and proceeds to the products side to reach dynamic equilibrium once again. Q is used to determine whether or not the reaction is at an equilibrium. The value of this constant can tell you which side (reactant or product) is favored. Thus, the reaction has to convert some of the reactants into products to come to equilibrium. Because the concentrations for \(N_2\) and \(H_2\) were given, they can be inserted directly into the equation. Sometimes, subscripts are added to the equilibrium constant symbol \(K\), such as \(K_\text{eq}\), \(K_\text{c}\), \(K_\text{p}\), \(K_\text{a}\), \(K_\text{b}\), and \(K_\text{sp}\). formula written above the arrow is used as a catalyst in the reaction (aq) reactant or product in an aqueous solution .

Since the numerator would have to be greater than the denominator in this case to yeild answer greater than 1, therefore the relative product concentration would have to be greater than that of reactants. What happens when a chemical reaction reaches equilibrium? This means that at equilibrium, the great majority of the material is in the form of products and it is said that the "products are strongly favored". K is the equilibrium constant. the Q equation is written by multiplying the activities (which are approximated by concentrations) for the species of the products and dividing by the activities of the reactants.
