Question

What happens to kinetic energy of molecules with increased temperature

Answer 1

The kinetic energy of molecules increase with the increase in temperature.

Step-by-step explanation:

when the temperature rises the individual molecules collide with each other, hence raising the kinetic energy.

considering the gas molecules:

K.E= 3/2 nRT

where R represents the universal gas constant

n represents the total number of moles

T represents the temperature

this equation clearly states that kinetic energy is directly related with the increase in temperature.

Answer 2

With increasing temperature, the kinetic energy of the molecules will increase and the reaction will take place.

Explanation:

A solution containing the reactant molecules at room temperature has low kinetic energy which is insufficient for reaction to take place. The kinetic energy will increases with the increase in colloidal motion between the molecules.

To break the old bonds the energy is needed and forms the new bonds to make a product known as activation energy. On increasing the temperature average kinetic energy of molecules in solution will increases due to increased vibration in the bonds of molecules that reaches activation energy that makes reaction takes place.
