Question
As the temperature of a chemical reaction increases, the rate of reaction increases becauseA fewer particle collisions occurB the required activation energy increasesC more effective particle collisions occurD the concentration of the reactants increases
Solution
The rate of a chemical reaction increases as the temperature increases because C: more effective particle collisions occur.
Here's why:
-
Increasing the temperature increases the kinetic energy of the particles involved in the reaction. This means that the particles move faster.
-
When particles move faster, they collide more frequently and with greater energy.
-
Not all collisions cause a reaction, only those with enough energy to reach the activation energy. With increased temperature, more collisions have enough energy to overcome the activation energy barrier.
-
Therefore, more effective collisions occur, leading to an increased rate of reaction.
So, the correct answer is C: more effective particle collisions occur.
