Reactants capable of interacting to form products in a chemical reaction must first overcome a thermodynamic barrier known as the reaction's
A)entropy.
B)activation energy.
C)endothermic level.
D)heat content.
E)free-energy content.

Question

Quizplus · Accepted Answer

The activation energy is the energy barrier that reactant molecules must overcome in order to undergo a chemical reaction and form products. This energy is necessary to break and rearrange chemical bonds in the reactant molecules in order to form new bonds in the product molecules. Once the activation energy is overcome, the reaction can proceed spontaneously and release energy.
