In an exothermic reaction, how does the enthalpy change (∆ r H) typically behave?

Options

  1. A∆rH is negative
  2. B∆rH is positive
  3. C∆rH remains constant
  4. D∆rH is zero

Correct answer

A. ∆rH is negative

Step-by-step solution

In an exothermic reaction, heat is evolved, and as a result, ∆ r H is negative.
