What does a negative ∆H value indicate in a chemical reaction?

Options

  1. AThe reaction is endothermic.
  2. BThe reaction is exothermic.
  3. CThe reaction is at equilibrium.
  4. DThe reaction has no enthalpy change.

Correct answer

B. The reaction is exothermic.

Step-by-step solution

A negative ∆H value indicates that the reaction releases heat (exothermic) to the surroundings.
