The video tutorial explains how activation energy and temperature influence chemical reaction rates. By maintaining a constant activation energy and varying temperature, it demonstrates that reaction rates double with a 10°C increase. The Arrhenius equation is applied to show that the rate constant is proportional to the exponential factor, which increases with higher temperatures and lower activation energies. The rate law is discussed, concluding that reducing activation energy and increasing temperature enhances the rate constant and reaction rate.
