Question

In an exothermic reaction, the bonding energy of the product is:


less than the reactants
same as the reactants
greater than the reactants
dependent on the presence of a catalyst

Answer 1

As in exothermic reactions Heat is Generated ,the energy to give away the heat comes from the bonding energy of the reactants..and the answer will be less than the reactants..

Answer 2

so in an exothermic reaction the products are greater than the reactions???!

Answer 3

Bonding energy of reactants=Bonding energy of product +HEAT
If heat>0
then
Bonding energy of reactants>Bonding energy of product

Answer 4

no ,that is not necessary,product's BONDING ENERGY will be lesser not the NO. OF PRODUCTS..

Answer 5

Ooooh ok, I get it...Can you help me with one more question

Which of the following reactions is not a chemical reaction?


melting an ice cube
tarnishing of a silver spoon
digestion of food
the browning of a freshly sliced apple

I Think its the digestion of food but im not sure

Answer 6

Look in digestion of food you have many chemical reactions going on in your organs,and with the help of these reactions only food is broken into smaller parts.
according to me the answer will be melting of ice as only the STATE OF MATTER is changing not matter itself.:)

Answer 7

Oh I thought that would be a physical change...
