Question

Find ∆G for a cell whose potential is +0.24 V with 4 moles of electrons exchanged.

Answer 1

Step 1. Use ∆G = -nFEo.

Step 2. Plug in n = 4, F = 96,500 and E = +0.24

Step 3. ∆G = -4 × 96,500 × 0.24 = -92,640 J = -92.64 kJ.

Answer 2

we need to use the following formula
Δ
`G= -nF E_(cell)`


`E_(cell)= 0.24V`
n= 4 moles
F= constant= 96500C/mol

let's plug in the values.

ΔG= -(4)(96500)(0.24)= -92640 J or -92.6 kJ
