Hello.
00:03
In this question, we are given two different parts.
00:06
So let's look at question number four first.
00:09
This is related to an endothermic reaction.
00:17
We are given different options and we're asked to figure out which is false.
00:23
So for an endothermic reaction, what happens is that heat is absorbed.
00:33
So that means that delta h is positive.
00:37
So when heat is absorbed, what happens is, that the heat is transferred from surroundings to system.
00:56
So this results in a temperature drop in surroundings and a temperature rise in system.
01:12
So now let's look at the options.
01:14
The first one says that the enthalpy change is positive which is true.
01:18
The second statement says that the heat passes from surrounding to the system which is also true.
01:23
The third statement says that the temperature of the surroundings decreases, which is also true.
01:29
And the fourth statement says that the temperature of the reaction system decreases, which is false...
