The rates of reactions increase with increase of temperature because
A.activating energy of the reacting molecules
B.kinetic energy of the product molecules increases
C.the fraction of the reacting molecules possessing✓ Correct
D.the collisions between molecules decrease.
Explanation
Shaded portion represent fraction of molecules possessing energy equal to or greater than a E & rate depends on fraction as a a E RT E RT k Ae k e As a E RT e increases i.e., fraction of molecules with energy equal to or higher increases. And thus, the rate of reaction increases
