Explanation:
The electrostatic forces are conservative forces!
The mainly property of the conservative fields is 
In spherical coordinates the field's expression is:

and the curl expression is:

to find the expression for the potential function associated:

Explanation:
A chemical reaction is a reaction in which two or more species combine together to form a molecule with a new chemical composition.
In a chemical reaction, the reactants are written on left hand side pointing a forward arrow towards the products which are written on the right hand side.
For example, chemical reaction between hydrogen and oxygen will result in the formation of water. The reaction equation will be as follows.
