Hello, student.
00:02
So in this question, you are given with the statement that says in the endothermic reaction, the options are given.
00:09
You have to choose the correct one.
00:10
First one says the energy is absorbed by the system.
00:14
Second one says the product is having lesser energy than the reactant.
00:18
And then the third one says that the product is having the same energy than the reactant.
00:23
And the d says the temperature of the system increases.
00:28
And the e says the heat flows out of the system.
00:31
So if you see the definition of endothermic reaction, here we have the endothermic reaction, endothermic reaction, right? for endothermic reaction, we have what? this endothermic reaction is when we give the energy, when we give energy to our products, to our products, sorry, to our reactants, not our products, to our reactants so that they may react with each other okay so as to react with each other react with each other fine so how we give this energy to the reaction so suppose we have to burn something right so this is the piece of paper and you want to burn this how you burn this you will first bring out a mat stick, right, bring out a mat stick which is already burning, which is already having a heat, and then you give this heat to this piece of paper, and then this will start to burn as well, right? so this, what you're giving is, what you're doing here is you are giving energy, you are giving, you are giving energy, sorry, okay, giving energy to a piece of paper.
02:20
So, as.
02:21
It may react with the fire to get to get heated or to get burnt right so here you can say that we are giving out the energy so if we if we give out the energy that means that our reactant that are reactants is having less energy less energy than product right that is why we need to give them energy if the product would have the more energy that will be exothermic reaction means that product will give us the energy back.
02:59
So in the endothomic we give energy to the system, sorry, we give energy to our reactants.
03:05
So if you see the options over here, so your first option says that this energy is absorbed by the system.
03:12
Yes, it is absorbed by the system because we give the energy to the system and that is absorbed...
