Given the equilibrium equation: H2(g) + Br2(g) 2HBr(g) If the partial pressure of H2 is increased, the equilibrium will shift to the right. If the partial pressure of H2 is decreased, the equilibrium will shift to the left. If the partial pressure of HBr is increased, the equilibrium will shift to the left.
Pressure. Increasing the pressure of a reaction improves the likelihood reactants will interact with each other, thus increases the rate of the reaction. As you would expect, this factor is important for reactions involving gases, and not a significant factor with liquids and solids.
