As exothermic reactions are defined as reaction in which energy is released and they are characterise as they have less energy of product then the energy of reactants.
As in the option 5 energy of product is less then reactant so energy is released so exothermic Ans e
1 & 2 are endothermic reaction as energy of product is more than the reactant so endothermic
