Rate Of Reaction Flashcards
1
Q
Concentration
A
More reactant particles in the same volume of a substance means that there is more to react with so a greater number of collisions.
2
Q
Surface area
A
More particles are exposed to the reactant so more collisions will happen.
3
Q
Temperature
A
The higher the temp the more kinetic energy the particles will have so they will move a lot faster and so there will be more collisions.
4
Q
Catalyst
A
They lower the activation energy by providing another pathway for reactions to occur.
5
Q
Three things you need for a reaction to hapen.
A
Speed:sufficient energy to overcome the activation energy barrier
Collision
Orientation: To form any new bonds in the products
