New cards

Rate of reaction

The speed at which reactants are used up or products are made

2
New cards

Collision theory

Particles must collide for chemical reactions to take place. These collisions must also happen with enough energy

3
New cards

Activation energy

The minimum energy with which particles must collide in order to cause a chemical reaction

4
New cards

How to answer rate of reaction question

more collisions per unit time → more successful collisions per unit time —> higher rate of reaction

5
New cards

How to do concentration vs rate of reaction

Different concentrations of sodium thiosulphate, react with hydrochloric acid, see how long it takes for solution to go cloudy

6
New cards

Surface area vs rate of reaction key information

React marble chips with hydrochloric acid. Use cotton wool plug to allow gas out but block acid from getting out
