Question

What will happen as the temperature of a system increases? a. The activation energy of the system will increase, causing an increased reaction rate. All the particles will have more kinetic energy causing more effective collisions. This will increase the reaction rate. The average kinetic energy of the particles will increase, causing more frequent collisions. This will decrease the reaction rate. The motion of the particles increases, causing more effective collisions, resulting in an increased reaction rate. b. c. d.

Explanation / Answer

Option c is false and other three are true.

a. Activation energy is directly proportional to temperature by Arrhenius equation & reaction rate also increases. Thus it's true.

b. Kinetic energy increases the particle move faster and collide more frequently per unit time and posses greater energy and in both cases reaction rate increases . Thus it's true.

c. As mentioned in b. Thus it's false.

d. Increases in temperature it increases motion of particles and causes more collisions with increases in reaction rate. Thus it's true.
