Chemistry What of the following options describes the term "dynamic equilibrium"? O a. A number obtained by multiplying the equilibrium concentrations of the products of a reaction, divided by the equilibrium concentrations of the reactants, raising each product and reactant concentration to the power of its stoichiometric coefficient. O b. Reversible processes ultimately reach a point where the rates in both directions are identical, so that the system gives the appearance of having a static composition at which the Gibbs energy, G, is a minimum. O c. An equation relating the equilibrium constant to the concentrations of the products and reactants of a reaction. O d. An equation that measures the relative amounts of products and reactants during a reaction at a particular point in time. It can be compared to the equilibrium constant to determine the direction the reaction would shift to reach equilibrium. O e. A general rule which predicts that when a system at equilibrium is perturbed, it would shift in the direction to counteract that perturbation
