heat is released in a chemical reaction during an exothermic reaction.
when is heat released in a chemical reaction?
exothermic reaction
heat production or absorption in either a physical process or chemical reaction is measured using calorimetry. one common laboratory instrument is the reaction calorimeter, where the heat flow into or from the reaction vessel is monitored. the technique can be used to follow chemical reactions as well as physical processes such as crystallization and dissolution.









































energy released is measured in joule per mole. the reaction has a negative δh(heat change) value due to heat loss.









































e.g.: -123 j/mol

reaction calorimeter









































a reaction calorimeter is a calorimeter that measures the amount of energy released (exothermic) or absorbed (endothermic) by a chemical reaction. these measurements provide a more accurate picture of such reactions.

when considering scaling up a reaction to large scale from lab scale, it is important to understand how much heat is released. at a small scale heat released may not cause a concern, however when scaling up, that heat can build up and be extremely dangerous.
