Question

Which of the following graphs represents exothermic
reaction?
(a) Only (I) (b) Only (II)
(c) Only (III) (d) Both (I) and (II)

Answer 1

Answer:

do insert the graphs please

Answer 2

The graph i shows exothermic reaction.

Explanation:

• Exothermic reaction is a type of reaction where heat is evolved from the system.

• This heat is generated from the reactions.

• This heat is the difference of energy levels of the reactant and products.

• Often the product that is produced from a reaction has different energy levels than that of the reactant.

• If the product has a higher energy level, that energy is achieved from the environment.

• Similarly if the product is lower than the reactant energy level, then the energy is emitted into the environment.

• That is felt as heat.

• This is shown in graph 1.
