Question

Which one is a true statement about endothermic reactions?

Question 2 options:

Energy is absorbed making it feel colder.


The reaction container always feels hot.


The reactants have less heat energy than the products.


More heat is given off than is put into the reaction.

Answer 1

The answer is Energy is absorbed making it feel colder. Endothermic reactions absorb heat from their environment (hence lowering the temperature of the nearby environment), unlike ectothermic reactions that release energy to their environment . The enthalpy of products in an endothermic reaction is higher than that of the reactant hence the change in enthalpy is positive.

Answer 2

-The reactants have less heat energy than the products.

Explanation;

-An endothermic reaction is a reaction in which heat energy is absorbed from the surroundings. In such a reaction the energy of the reactants is less than the energy of the products and therefore the enthalpy change is positive, greater than zero.
