Question
Which way will the equilibrium shift, for the endothermic reaction below, if a catalyst is added (and everything else is held constant)?N2O4(g) 2NO2(g)Group of answer choicesTo the left (more reactants)To the right (more products)It will not shift
Solution
The addition of a catalyst to a reaction does not shift the equilibrium. A catalyst works by lowering the activation energy for both the forward and reverse reactions, which speeds up both reactions equally. Therefore, the equilibrium position does not change. So, the answer is "It will not shift".
