What Is the Rate Law for the Uncatalyzed Reaction of Cerium and Thallium Ions?
Homework Statement 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...- shawonna23
