Transcript

00:02 In the 14th question it is asked an exothermic reaction heat can be considered as a so an exothermic reaction is a reaction in which heat is liberated as a result of the reaction and the temperature of the surrounding increases while in an endothermic reaction heat is absorbed so activation energy of a reaction is the minimum energy required for a reaction to occur these are some of the basics which are related to these questions minimum energy required for a reaction to occur it is a difference between the initiation stain which is the reactors and the finest in which are the products and transition energy is the energy of transition state formed in between the reaction.

01:46 So for 14th question which asks for an exothermic reaction, heat is considered as a product because in an exothermic reaction heat is liberated.

02:00 So heat is considered as a product.

02:02 So correct option is option b.

02:05 Now for 15th question which asked, any reaction that absorbs 150 kilo calorie of energy can be classified as.

02:23 So, an reaction that absorbs energy is called as an endothermic reaction.

02:30 So correct answer is given by option a, which is endothermic.

02:46 The 16th question asks, the dash is the energy difference between reactants and products in a chemical.

02:54 Reaction.

02:57 So activation energy which is the minimum energy for a reaction to occur is a difference between the reactants and products.

03:05 Therefore the correct answer is option b which says activation energy...
