What is the free energy change in kJ for the reaction below?

2 ClO₃⁻(aq) + 12 H⁺(aq) + 5 Co(s) → Cl₂(g) + 6 H₂O(l) + 5 Co²⁺(aq)

E° = 1.564 V.

Expert Solution

Step 1

Gibbs free energy change is calculated by the formula

∆G=-nFE°

Where,

∆G = Gibbs free energy change

F= Faraday constant

E°= standard cell potential

n= number of electrons involved

If gibbs free energy change comes out to be negative then reaction is spontaneous and if it comes out to be postive then the reaction is non-spontaneous.
