Indicate how the concentration of each species in the chemical equation will change to reestablish equilibrium after changing th
e 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
After the concentration of H₂ is decreased, there will not be enough H₂ to from HBr, so the concentration of HBr will decrease, and the concentration of Br will increase.
After the concentration of HBr is increased, there would be more HBr that will give more H₂ and Br₂.
