Question
Which way will the equilibrium shift, for the exothermic reaction below, if a catalyst is added (and everything else is held constant)?H2(g) + I2(g) 2HI(g)Group of answer choicesTo the left (more reactants)To the right (more products)It will not shift
Solution
The equilibrium will not shift. A catalyst speeds up both the forward and reverse reactions equally by lowering the activation energy. Therefore, it does not change the position of the equilibrium; it only helps the reaction reach equilibrium faster.
