When a reaction is endothermic,
Enthalpy change, \(\Delta\)H is negative
Heat content of a product is less than the heat content of a reactant
Heat content of reactants is less than the heat content of product
The reaction is non-spontaneous
Magyarázat
An endothermic reaction is any chemical reaction that absorbs heat from its environment. The absorbed energy provides the activation energy for the reaction to occur.
