Consider the chemical system: A(g) + 3 B(g)  ⇋  C (g)K = 6 x 1012   How do the equilibrium concentrations of the reactants compare to the equilibrium concentration of the product?Question 1Select one:a.Reactant and product concentrations have to be exactly equal at equilibriumb.You can't tell from the information given because of the stoichiometryc.Reactant concentrations are much lower, products dominate at equilibrium.d.Reactant and product concentrations are about the same order of magnitudee.Reactant concentrations are much higher, reactants dominate.
