cell potential

Postby Clara Cho 2K » Sun Mar 01, 2020 4:43 pm

how can you tell if the reaction will favor the forward or reverse process from the E value?

When the Cell Potential is positive, this refers to a negative delta G and therefore a spontaneous reaction which proceed over time, not necessarily in a fast manner.

From the equation deltaG = -nFE, we can determine if a reaction is favored or not.

If E (cell potential) is positive, deltaG is negative and thus will be spontaneous.
If E is negative, deltaG will be positive and therefore non-spontaneous.

deltaG=-nFEcell
if Ecell is positive, delta G will be negative meaning the reaction is spontaneous. If Ecell is negative, deltaG will be positive meaning the reaction will not be spontaneous

Delta G will be negative meaning the reaction is spontaneous, if Ecell is positive. However, if Ecell is negative, deltaG will be positive. This means that the reaction will not be spontaneous

If the E cell value is positive, the delta G is negative, and K is greater than one. If the E cell value is negative, the delta G is positive, and K is less than one.

When E is positive, delta G will be negative. This would mean that the reaction will be spontaneous. However, when E is negative, delta G will be positive. This would mean that the reaction will be non-spontaneous.

When E is positive, delta G is negative and therefore spontaneous.

If the cell potential for a reaction is positive that means that delta G is negative meaning the reaction is spontaneous.

When the cell potential is positive it means the forward reaction will be favored as it is spontaneous. If the cell potential is negative, then the reverse reaction is spontaneous and will be favored.

When E is positive, the reaction will be spontaneous. However, when E is negative, the reaction will be nonspontaneous.

delta G=-nFE, so if there is a positive cell potential (E) then delta G is negative, making it a spontaneous reaction.

If the E value is positive, this means that the deltaG value is negative, so the process is spontaneous.

When E is positive and delta G is negative, spontaneity is involved

deltaG = -nFE, so if E is positive, deltaG would be negative, showing that the reaction is spontaneous. If E is negative, then deltaG is negative, showing that the reaction is not spontaneous.
