Races Of Reactions Flashcards
Why does decreasing particle size increase the rate of reaction?
There is greater surface area exposed, which increases the chance of successful collisions, which leads to an increase in rate.
Why does increasing concentration increase the rate of reaction?
There are more particles moving in the same space, meaning there is more chance of successful collisions happening, leading to an increased rate of reaction.
Why does increasing the temperature increase the rate if reaction?
The reactant particles move much quicker, and more particles have the activation energy. The particles collide more often, with more force, and more of the collisions result in areaction.
What is the activation energy?
The minimum kinetic energy required for a reaction to occur
What are the two requirements for particles to react successfully?
Particles must have the correct activation energy along with the correct geometry
What is an activated complex?
Anactivated complexis anunstable arrangement of atoms that exists momentarily at the peak of theactivationenergy barrier, which then breaks down to form the products of the reaction.
