Question on: SS3 Chemistry - Chemical Thermodynamics
Which of the following statements about Hess's Law is correct?
Hess's Law states that the enthalpy change of a reaction is directly proportional to the temperature.
Hess's Law allows the calculation of the enthalpy change of a reaction based on bond energies.
Hess's Law states that the enthalpy change of a reaction is independent of the reaction pathway.
Hess's Law is only applicable to exothermic reactions.
Hess's Law is a fundamental principle in thermodynamics that states the enthalpy change of a reaction is independent of the reaction pathway taken from reactants to products. In other words, the overall enthalpy change of a reaction remains the same, regardless of the intermediate steps involved in the reaction.
