Question

. As the temperature of a reaction is increased, the rate of the reaction increases because of the
__________.
A. Reactant molecules collide less frequently
B. Reactant molecules collide more frequently and with lesser energy per collision
C. Activation energy is lowered
D. Reactant molecules collide more frequently and with greater energy per collision

Answer 1

Answer:

D is the answer i think

Answer 2

As the temperature of a reaction is increased, the rate of the reaction increases as Reactant molecules collide more frequently and with greater energy per collision (option - D)

• Temperature increases both the number and effectiveness of collisions of reactant molecules.
• As per the collision theory, as the temperature is increased - the speed of reactant particles increases, therefore increasing the kinetic energy of the particles.
• Hence, increasing temperature increases the chance of reactants colliding together as well as ensures greater energy per collision.
