A reaction that releases energy is called "Exothermic" - exuding heat. A reaction that requires energy is called "Endothermic" - to put in heat.
Exothermic reactions are generally more stable than endothermic ones because they release energy to their surroundings that is available for work to be done, where as endothermic reactions absorb energy from their surrounds and are therefore doing work.

Hi. Burning paper releases energy. Making plastic requires energy.

u term such equation as exothermic and endothermic rxns
exothermic in which energy is released and endothermic in which energy is consumed by the products formed
mainly the difference is that in exothermic rxns the initial energy possessed by the reactant is greater than its product formed therefore the product formed possessed less energy and energy that is lost is given out to the surroundings
whereas endothermic rxns r those in which initial energy possessed by reactant is less than that is possessed by reactants resulting in absorption of energy
