If the reduction reaction has a reduction potential of 0.1 v, and the oxidation reaction has a reduction potential of -0.4v, and 2 electrons were transfered, what is the value of delta g expressed in terms of f?

Answer : The value of ΔG expressed in terms of F is, -1 F

Explanation :

First we have to calculate the standard electrode potential of the cell.

or,

Now we have to calculate the standard cell potential.

Formula used :

where,

= Gibbs free energy = ?

n = number of electrons = 2

F = Faraday constant

= standard e.m.f of cell = +0.5 V

Now put all the given values in this formula, we get the Gibbs free energy.

Therefore, the value of ΔG expressed in terms of F is, -1 F

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
