Indicate how the concentration of each species in the chemical equation will change to reestablish equilibrium after changing the concentration of the reactant or product. An up arrow indicates an increase in concentration, a down arrow indicates a decrease in concentration, and leaving it blank means there is no change in the concentration H2(g) Br2(g) 2HBr(g) after the concentration of H2 is decreased after the concentration of HBr is increased
