Answer :
The correct statement describing an endothermic chemical reaction is:
B The products have higher potential energy than the reactants, and the change in heat is positive.
Explanation:
1. In an endothermic reaction, energy is absorbed from the surroundings, causing the products to have higher potential energy than the reactants.
2. The change in heat in an endothermic reaction is positive because heat is being absorbed, leading to an increase in the energy of the system.
3. This type of reaction often feels cold to the touch because it is drawing heat in from its surroundings to proceed.
Therefore, option B is the correct description of an endothermic chemical reaction.
