The manganese(II)-catalyzed redox reaction between cerium(IV) and thallium(I) is thought to proceed by a three-step mechanism: Ce4+(aq) + Mn2+(aq) --> Ce3+(aq) + Mn3+(aq) (slow) Ce4+(aq) + Mn3+(aq) --> Ce3+(aq) + Mn4+(aq) Mn4+(aq) + Tl+(aq) --> Mn2+(aq) + Tl3+(aq) (a) If the first step of this mechanism is rate-determining (slow), choose the correct rate law for the overall process. Rate = k [Mn2+] [Mn3+] Rate = k [Ce4+]2     Rate = k [Ce4+] [Tl+] Rate = k [Mn2+] [Ce4+] Rate = k [Ce4+]2 [Tl+] Rate = k [Mn3+] [Tl+]

Question

The manganese(II)-catalyzed redox reaction between cerium(IV) and thallium(I) is thought to proceed by a three-step mechanism:

Ce4+(aq) + Mn2+(aq) --> Ce3+(aq) + Mn3+(aq) (slow)
Ce4+(aq) + Mn3+(aq) --> Ce3+(aq) + Mn4+(aq)
Mn4+(aq) + Tl+(aq) --> Mn2+(aq) + Tl3+(aq)



(a) If the first step of this mechanism is rate-determining (slow), choose the correct rate law for the overall process.


Rate = k [Mn2+] [Mn3+]
Rate = k [Ce4+]2    
Rate = k [Ce4+] [Tl+]
Rate = k [Mn2+] [Ce4+]
Rate = k [Ce4+]2 [Tl+]
Rate = k [Mn3+] [Tl+]
