Question

how can we identify whether something is exothermic or endothermic? at which side we should be looking while telling this... reactant or the product side?​

Answer 1

Answer:

So if the sum of the enthalpies of the reactants is greater than the products, the reaction will be exothermic. If the products side has a larger enthalpy, the reaction is endothermic. You may wonder why endothermic reactions, which soak up energy or enthalpy from the environment, even happen.

Answer 2

Answer:

we can tell or identify whether something is endothermic or exothermic by the following points ..

• In endothermic. heat is taken for reaction that is taking place on the rectant side.
• but in exothermic ,the heat is relased during the reaction on the product side..
• hope it will help you...
