Answer:
Manganese (II) ion, Mn²⁺
Explanation:
Hello,
In this case, given the overall reaction:
Thus, since manganese (II) ion, Mn²⁺ is both at the reactant and products, we infer it is catalyst, since catalysts are firstly consumed but finally regenerated once the reaction has gone to completion. Moreover, since inner steps are needed to obtain it, we can infer that the given rate law corresponds to the slowest step that is related with the initial collisions between Ce⁴⁺ and Mn²⁺
Best regards.

Detachment from reality (delusions), paranoia or hallucinations
Inability to cope with daily problems or stress
Trouble understanding and relating to situations and to people
Problems with alcohol or drug use
Major changes in eating habits
To solve this we use the equation,
<span>M1V1 = M2V2</span>
<span>where M1 is the concentration of the stock
solution, V1 is the volume of the stock solution, M2 is the concentration of
the new solution and V2 is its volume.</span>
0.25<span> M x V1 = 0.15 M x .500 L</span>
<span>
V1 = 0.3 L or 300 mL</span>
