Question

In an exothermic reaction, $\Delta H$ is:

• A. positive
• B. negative
• C. zero
• D. may be positive or negative

Answer 1

The correct option is B negative

Exothermic reaction is a reaction in which net energy is released in a reaction.
i.e, $\Delta H=\text{(energy of products) -( energy of reactants)}<0$
Hence, answer is option $B$.
