What is the main purpose of using NaOH in the saponification reaction . NaOH works as the catalyst b. NaOH solution is the solvent for the reaction c. NaOH acts as a reactant in the reaction d. NaOH facilitates the soap to salt out from the solution

C. NaOH acts as a reactant in the reaction

Explanation:

Because during the saponification process, Na+ replaces the H+ in the fatty acid been used for the saponification process

b is the correct

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
