For a reaction to occur, the energy of the system must meet the activation energy threshold.

Which best explains why increasing the temperature increases the rate of a reaction?

A) Because more particles spread out away from each other
B) Because more particles swell and occupy more space
C) Because more particles move with greater speed and collide more frequently
D) Because more particles experience a greater force of attraction between them

I want to say C or D but I'm not necessarily sure....

Bruv whats the answer

temperature is a measure of the average kinetic of the particles

higher temperature means faster moving particles

faster particles collide with more impact energy (for activation)

Okay, thank you!

I believe its C. Because more particles move with greater speed and collide more frequently

due to the fact of R_Scott explanation of moving particles and collision with each other is a occurrence when particles have more energy

To determine the correct answer, let's analyze the options and relate them to the concept of temperature and reaction rate.

A) "More particles spread out away from each other"
This option does not directly explain why increasing temperature increases the rate of a reaction. It mentions that particles spread out, but it does not provide any information about the effect this has on reaction rates.

B) "More particles swell and occupy more space"
Similarly, this option talks about particles occupying more space without directly addressing the impact on reaction rate.

C) "More particles move with greater speed and collide more frequently"
This option is a more accurate explanation. Increasing the temperature of a system provides energy to the particles, causing them to move faster. With greater speed, the particles collide more frequently, increasing the chances of successful collisions between reactant molecules. Higher collision frequency leads to a higher reaction rate.

D) "More particles experience a greater force of attraction between them"
While temperature can affect the strength of intermolecular forces, this option does not directly explain why increasing temperature increases the reaction rate.

Based on the explanations provided, the correct answer is C) "Because more particles move with greater speed and collide more frequently."
