Calculate the effect of adding a catalyst on the equilibrium position of the following redox reaction: Fe2+(aq) + H2O2(aq) + 2H+(aq) ⇌ Fe3+(aq) + 2H2O(l) If a catalyst is added to the reaction mixture, what will be the new equilibrium constant (Kc)? And how will the addition of a catalyst affect the value of Kc?
