Respuesta :
A + B + heat → C+D among the following indicates an exothermic reaction, therefore option (b) is correct.
What do you mean exothermic reaction?
An exothermic reaction is a reaction that is associated with a release of energy into the environment. This energy released is in the form of heat.
So, the reaction has a negative enthalpy value. As more energy is released during the making of a chemical bond, exothermic reaction is associated with the making of new bonds.
These are reactions that transfer energy to the surroundings .
