standard reduction potential

[Deepika Pugalenthi 1A]

When calculating standard reduction potential, is there ever an instance when you would multiply or divide the standard reduction potential? Or is it only sign change based on which direction the reaction proceeds?

[Swetha Ampabathina1I]

I believe that the half reactions can be multiplied in order to achieve the balanced equation but that won't change the value of e°since that is an intensive property, so only sign changes for standard reduction potentials.

E will not change since it is intensive however depending on the direction of the equation you might change its sign.
