In a chemical reaction, delta H represents the sum of the heats of formation, commonly measured in kilojoules per mol (kJ/mol), of the products minus the sum of those of the reactants. The letter H in this form is equal to a thermodynamic quantity called
For most reactions, the value of {eq}\Delta {/eq}U is very close to that for {eq}\Delta {/eq}H. True False Thermodynamics: In Chemistry, thermodynamics is key: It encompasses a series of parameters like enthalpy, entropy, and Gibbs free energy. The above ...
