Statement II is true for a catalyst, as it provides a new pathway for the reaction to occur through. Statement III is also true, as the catalyst speeds up the reaction by lowering the activation energy required for the reaction to proceed. Statement I is not necessarily true for all catalysts, as some may remain unchanged during the reaction or be regenerated at the end of the reaction.
