Indicate whether each statement is true or false. (c) Increasing the reaction temperature increases the fraction of successful collisions between reactants.

Key Concepts

Collision Theory

Collision theory states that for a reaction to occur, reactant particles must collide with sufficient energy and proper orientation. The frequency and energy of these collisions are influenced by factors such as temperature, which affects the kinetic energy of the particles.

Effect of Temperature on Reaction Rate

Increasing the temperature generally increases the kinetic energy of molecules, leading to more frequent and more energetic collisions. This results in a higher fraction of collisions that have enough energy to overcome the activation energy barrier, thus increasing the reaction rate.

Activation Energy

Activation energy is the minimum energy required for a chemical reaction to occur. When temperature rises, more molecules possess energy equal to or greater than this threshold, which increases the likelihood of successful collisions and, consequently, the rate of reaction.
