Question

Using the table of standard reduction potentials, what is the reduction potential of the cell that produces the following chemical reaction?

2Fe3+ + Zn --> 2Fe2+ + Zn2+

A. −0.01 V
B. 0.77 V
C. 0.01 V
D. 1.53 V

Answer 1

@diamondboy I got it wrong...it's not B. What did you get?

Answer 2

what was d reduction half reaction again?

Answer 3

2Fe3+ ------> 2Fe2

Answer 4

you need to do this one step at a time. if all you're doing is guessing with a half-finished idea, you wont' actually learn much

Answer 5

what's the potential for that reduction from the table?

Answer 6

I don't know. Can you explain it quickly? I don't have much time left...

Answer 7

do u have d table?

Answer 8

No I don't

Answer 10

sorry its so long but dats d table

Answer 11

I have to submit this is 7 minutes or I'll fail! Can you please explain it quickly?

Answer 12

its 0.77

Answer 13

its C

Answer 14

thanks :)

Answer 15

did u get it?

Answer 16

0.77 or 0.01?

Answer 17

sorry 0.77

Answer 18

ok thanks

Answer 19

it was wrong. the answer is D.

Answer 20

OMG I am so sorry

Answer 21

I know why now

Answer 22

for d half oxidation reaction we were to flip d value of E it was negative on d table we were to make it +ve then add it to 0.77
