HEAT OF REACTION

1. HEAT OF REACTION😉

2. WHAT IS HEAT OF REACTION?

3. •heat of reaction, the amount of heat
that must be added or removed during
a chemical reaction in order to keep all
of the substances present at the same
temperature. If the pressure in the
vessel containing the reacting system is
kept at a constant value,the measured
heat of reaction also represents the
change in the thermodynamic quantity
called enthalpy, or heat content,

7. WHAT IS
CHEMICAL REACTIO

12. TWO TYPES OF
CHEMICAL REACTION

13. ENDOTHERMIC

14. Breaking a chemical bond
requires energy and
therefore is
Endothermic.Breaking a
chemical bond requires
energy and therefore is
Endothermic.

15. EXOTHERMIC
REACTION

16. •exothermic reaction is a
chemical reaction that
releases energy by light
or heat.It is the opposite
of an endothermic
reaction.
