Question

Thermal energy has an impact on chemical reactions because

Group of answer choices

It makes molecules melt so they can mix together like a liquid

It increases the number of collisions between reactants

It makes atoms and molecules in the reactants more sticky

It brings reactants closer together so they are sitting side by side

Answer 1

The correct answer is "It increases the number of collisions between reactants".

Step-by-step explanation:

In chemistry, activation energy is defined as the amount of energy needed for compounds to perform a chemical reaction. Thermal energy decreases activation energy, which results on higher reaction rates. This is explained by the increase of entropy that results by increasing the thermal energy, which increases the number of collisions between reactants. Compounds and particles only react when they collide, if the particles are heated they move faster and collide more frequently.
