The nernst equation is illustrated by the image below.

To compute for nernst equation, four essential parameters are needed and these parameters are **Electrochemical Cell Potential (ΔV°), Number of Electrons (n), Molar Concentration [M _{1}^{n+}]** and

**Molar Concentration [M**

_{2}^{n+}].The formula for calculating nernst equation:

ΔV = ΔV° – ^{0.0592}/_{n} log(^{M1n+}/_{M2n+})

Where:

ΔV = Nernst Equation | Potential

ΔV° = Electrochemical Cell Potential

n = Number of Electrons

M_{1}^{n+} = Molar Concentration

M_{2}^{n+} = Molar Concentration

Given an example;

Find the nernst equation when the electrochemical cell potential is 3, the number of electrons is 9, the molar concentration is 6 and the molar concentration is 2.

This implies that;

ΔV° = Electrochemical Cell Potential = 3

n = Number of Electrons = 9

M_{1}^{n+} = Molar Concentration = 6

M_{2}^{n+} = Molar Concentration = 2

ΔV = ΔV° – ^{0.0592}/_{n} log(^{M1n+}/_{M2n+})

ΔV = 3 – (^{0.0592}/_{9}) log(^{6}/_{2})

ΔV = 3 – (0.00657) log (3)

ΔV = 3 – 0.0065 (0.477)

ΔV = 3 – (0.0031)

ΔV = 2.99

Therefore, the **nernst equation **is **2.99 V.**
