When a reaction is endothermic,
...When a reaction is endothermic,
Enthalpy change, ΔH 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
Correct answer is C
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.
