endothermic and exothemic reactions (1 Viewer)

[Iunny]

I don't understnad them, can someone plz explain?

Do these reactions have anything to do with breaking and making bonds?

e.g.

Breaking bonds require a lot of energy therefore, it is an endothermic reaction

making bonds releases energy and its an exothermic reaction

thx

it depends on the total internal energy of the reactants and products... if you have the internal energy of the product less than your reactant then you have an exothermic reaction...

other wise, you have an endothermic reaction...

but yea, breaking bond requires energy and forming bond releases energy...
