What is it?
A formation reaction is when all the reactants (left side of the equation) are elements and the coefficient for the single product (there can only be 1 product) must be 1.
To have the coefficient of 1 for the product you may need to use fractional coefficients for the reactants
When 1 mole of compound is formed with elements in their standard states it’s known as Enthalpy Formation
Example of Formation Reaction
C (s) + O
C (s) +
