Heat is added to a chemical system. Which energy will increase?(1 point)

Question

the potential energy of the products
the relative potential energy of the system
the activation energy of the system
the kinetic energy of the reactant molecules

Answer 1

When heat is added to a chemical system, the energy that will increase is the kinetic energy of the reactant molecules.

Adding heat to a system typically increases the temperature, which, in turn, increases the motion of the molecules (their kinetic energy). This increase in kinetic energy can help reactants overcome the activation energy barrier, allowing reactions to occur more readily.
