Question

Please explain endothermic and exothermic reaction in simple words and clearly with examples...No spam plzzz
IT'S URGENT

Answer 1

endothermic reaction is a reaction in which energy is absorbed and exothermic reaction is a reaction in which gas is evolved along with the formation of product example for exothermic reaction C + O2 gives CO2 + heat example for endothermic reaction CaCO3 heats and gives c a o + CO2

Answer 2

*exothermic reaction involve increase in temperature whereas endothermic invoves decrease in temperature
*exothermic reaction release heat during reaction whereas endothermic reaction require heat for reaction....
*eg of exothermic is combustion and eg of endothermic is melting of ice......

hope it is helpful.....
