Question
Which way will the equilibrium shift, for the exothermic reaction below, if a catalyst is added (and everything else is held constant)?N2(g) + 3H2(g) 2NH3(g)Group of answer choicesTo the left (more reactants)To the right (more products)
Solution
The addition of a catalyst to a reaction does not shift the equilibrium to the left or the right. A catalyst works by lowering the activation energy for both the forward and reverse reactions, which increases the rate at which both reactions occur. However, it does not change the equilibrium position of the reaction. Therefore, the equilibrium will not shift to the left or the right when a catalyst is added.
