## Why is gas constant used in Nernst equation?

As the Nernst equation compares the “osmotic pressure” to “electrical pressure”, the universal gas constant is needed **to convert amount of an ion on the two sides of a membrane (“osmotic concentrations”) to the amount of energy associated with that concentration differential (“osmotic pressure”)**.

## What is the universal gas constant in the Nernst equation?

R

R is the gas constant = **8.314 J/K Mole**.

## Why is the universal gas constant important?

Explanation: It is only important **if you want to relate the pressure or the volume or the moles or the temperature of a gas to any of the other values**. It is a proportionality constant for the ration of PVnT ,where P is pressure, V is volume, n is moles of the gas, and T is the temperature in Kelvin.

## What is the purpose of the Nernst equation?

The Nernst equation **defines the relationship between cell potential to standard potential and to the activities of the electrically active (electroactive) species**. It relates the effective concentrations (activities) of the components of a cell reaction to the standard cell potential.

## What is the value of universal gas constant in Nemst equation when the potential is given in volts options?

**pH= 3.73**. 10. What is the value of universal gas constant in Nernst equation when the potential is given in volts? Explanation: The universal gas constant is denoted by R and is expressed in units of energy per temperature per mole.

## What is the value of the equilibrium constant K for the redox reaction that occurs in a concentration cell?

3.16 x 10^{282}

Answer: The equilibrium constant of the cell’s redox reaction is **3.16 x 10 ^{282}**.

*The Nernst equation is written as ESL equals to e naught cell minus RT by NF Ln. C concentration C D concentration D by a concentration a B concentration be at equilibrium ESL equals to 0.*

## When should the Nernst equation be used?

Use the Nernst equation **to determine cell potentials at nonstandard conditions**. Perform calculations that involve converting between cell potentials, free energy changes, and equilibrium constants.

## What is the Nernst equation and what does it tell us about ion transport?

You probably recognise equation 1 as the Nernst equation. This equation defines the relation between the concentrations of an ion on either side of a membrane that it perfectly selective for that ion and the potential difference (voltage) that will be measured across that membrane under equilibrium conditions.

## Where does Nernst equation come from?

The Nernst Equation is derived from **the Gibbs free energy under standard conditions**. E is potential difference.
