In chemistry, one often uses a unit of charge known as the faraday, f, which has the magnitude of the charge of 1 mole of electrons. how many coulombs are there in a faraday

 96500 Coulombs are there in a Faraday.

Explanation:-

It is given that 1 mole of electrons has charge of 1 Faraday.

Moles of electron = 1 mole

According to mole concept:

1 mole of an atom contains number of particles.

We know that:

Charge on 1 electron =

Charge on 1 mole of electrons =      

Thus 96500 C= 1 Faraday

Thus 96500 Coulombs are there in a Faraday.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
