Rates Of Reaction Flashcards
What is a catalyst in an organic reaction called?
Enzyme
What dose a catalyst do?
Increase rate of reaction without being used up
How does increasing temperature affect a reaction?
It causes the particles to have more energy and move faster resulting in more successful collisions and a faster rate of reaction
How dose increasing surface area affect rate of reaction?
Increasing surface area increases rate of reaction because there are more particles available to collide with
How does concentration affect rate of reaction?
There are more particles so more chance of successful collisions so it increases rate of reaction
How dose increasing the pressure affect rate of reaction?
The particles have less room to move so they are more likely to collide
What is activation energy?
The amount of energy needed to start a reaction
