This question asks for which statement is true regarding an exothermic reaction.
00:07
Let's just briefly go over the concept of an exothermic reaction.
00:11
So first we have a reaction which have reactants for main products.
00:22
And let's just consider their potential energy.
00:25
Let's say there are two different states.
00:27
One has a high potential energy and one has a lower potential energy.
00:31
If the reactants have a higher potential energy and the products have a lower potential energy, then from the reactants to product, it is considered a exothermic reaction, and during this reaction, energy will be released.
00:54
And if the reactants have a lower potential energy state, and the products have a higher potential energy state, from reactants to product, this is considered an endothermic reaction, and energy is required for this reaction, meaning that it needs an outer source of energy.
01:22
So let's go over the option and see which one is the correct one.
01:27
A talks about that the products have a lower potential energy than the reactants.
01:31
So as we know, that product, for an exothermic reaction, the products have a lower potential energy, and the reactants have a higher potential energy.
01:42
Therefore, option a is the correct answer...
