Question

Which one is a true statement about endothermic reactions?

A) The reaction container always feels hot.

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

C) The reactant have less heat energy than the products.

D) Energy is absorbed making it feel colder.

Answer 1

I completely agree that it is D) Energy is absorbed making it feel colder!

Answer 2

Answer;

D) Energy is absorbed making it feel colder.

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.

An endothermic reaction occurs when the energy used to break the bonds in the reactants is greater than the energy given out when bonds are formed in the products. This means that overall the reaction takes in energy, therefore there is a temperature decrease in the surroundings.
