PRETEST ON COLLISION THEORY

In the collision theory, reactions occur when particles collide with sufficient energy and proper orientation.

• TRUE

• FALSE

Increasing the temperature of a reaction generally increases the rate of reaction according to collision theory. Higher temperature provides more kinetic energy to the particles, leading to more frequent and energetic collisions.

• TRUE

• FALSE

Increasing the concentration of reactants typically increases the rate of reaction according to collision theory. Higher concentration results in a higher number of collisions between particles, increasing the likelihood of successful collisions.

• TRUE

• FALSE

A higher activation energy barrier generally leads to a slower rate of reaction according to collision theory. The higher the activation energy, the fewer particles possess enough energy to overcome the barrier and react.

• TRUE

• FALSE

Catalysts can increase the rate of reaction by providing an alternative pathway with a lower activation energy. This lowers the energy barrier, allowing a larger number of particles to successfully react.

• TRUE

• FALSE
