The hydrolysis of phosphoenolpyruvate proceeds with a δg'° of about - 62 kj/mol. the greatest contributing factors to this reaction are the destabilization of the reactants by electrostatic repulsion and stabilization of the product pyruvate by:

tautomerization

Explanation:

Tautomerization is defined as a phenomenon whereby two molecules known as tautomers have different conductivity and similar molecular formula. Thus, in the given chemical reaction, the main contributing variables to the chemical reaction which are the destabilization of reactants by electrostatic repulsion and stabilization of the product formed pyruvate by tautomerization.
