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?

Rate of reaction= k [Ce^3+]^2 [Tl^3+]

Explanation:

Since the reaction is thought to occur in a single reaction step for the uncatalysed reaction, and the reaction equation is: 2Ce4+(aq)+Tl+(aq)→2Ce3+(aq)+Tl3+(aq)

Rate of reaction= k [Ce^3+]^2 [Tl^3+]

Note that the rate of reaction = rate of appearance of products or rate of disappearance of reactants as shown above.

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=
