The reaction H2O2 --> H2O + O2 could be catalyzed by either MnO2 or beef liver, which contains the enzyme catalase. In either case, the catalyst:
raises the energy of the reactant.
lowers the energy of the products.
lowers the energy of the transition state.
shifts the equilibrium concentrations further to the product side of the reaction.
inhibits the reverse reaction.
