Which of the following statements about enthalpy change (∆H) for a chemical reaction is correct?

Options

  1. A∆H is the same for all reactions.
  2. B∆H depends on the stoichiometry of the reaction.
  3. C∆H is always positive.
  4. D∆H is unrelated to the reactants and products.

Correct answer

B. ∆H depends on the stoichiometry of the reaction.

Step-by-step solution

∆H depends on the specific reaction and the stoichiometry of reactants and products involved. It can vary for different reactions.
