collision theory Flashcards
activation energy
the energy required for particles to collide and react with eachother
factors that effect rate of reaction in particles
- amount of energy in particles
- frequency of collisions
- temperature
- concentration
- surface area
how does the amount of energy in particles effect rate of reaction
more energy can be transferred during the collision
how does frequency of collisions affect rate of reaction
the more they collide, the more successful collisions there will be
how does concentration/pressure affect rate of reaction
there will be more particles per volume and therefore more collisions will occur
how does surface area affect rate of reaction
there will be a higher area in which collisions with reactants take place, therefore leading to higher frequencies of collisions
define FULLY what a catalyst is
speeds up the rate of reaction by lowering the activation energy and providing alternate pathways for the reaction
