Metals often form several cations with different charges. cerium, for example, forms ce3+ and ce4+ ions, and thallium forms tl+ and tl3+ ions. cerium and thallium ions react as follows: 2ce4+(aq)+tl+(aq)→2ce3+(aq)+tl3+(aq ) this reaction is very slow and is thought to occur in a single elementary step. the reaction is catalyzed by the addition of mn2+(aq) according to the following mechanism: ce4+(aq)+mn2+(aq)ce4+(aq)+mn3+(aq)m n4+(aq)+tl+(aq)→→ →ce3+(aq)+mn3+(aq)ce3+(aq)+mn4+(aq) mn2+(aq)+tl3+(aq) part a what is the rate law for the uncatalyzed reaction?
