1
New cards

rate of reaction

how fast a reaction occurs over a specific time

2
New cards

changes the rate of reaction

-surface area (solid reactants)

-concentration (liquid/solution)

-temperature

-catalyst

-pressure (gas)

3
New cards

collision theory

particles must collide to react, to have a successful collision:

-right amount of energy

-correct angle

4
New cards

bigger surface area

increases collision —> increases rate of reaction

5
New cards

higher temperature

more energy —> more frequent collisions —> increases rate of reaction

6
New cards

concentration

more particles for collision —> increase rate of reaction

7
New cards

catalyst

lower activation energy needed —> increases rate of reaction
