Question

What can be said about a redox reaction that has a positive potential?

A. Energy must be added to cause the reaction.
B. The reaction will be spontaneous.
C. The reaction will be nonspontaneous.
D. Both half-reactions must have positive potentials.
I'm 99% sure its B.

Answer 1

sorry guys for the overload of questions. I have a really important exam tomorrow

Answer 2

it is B, GJ

Answer 3

the equation that verifies this is \[\Delta G = -nFE^0\]

Answer 4

if \(E^0\) is positive, n is always positive, and F is always positive, then \(\Delta G\) will be negative, thus the reaction is spontaneous

Answer 5

you're awesome at chemistry.

Answer 6

thanks for the explanation
