37
Q

Two ways to measure rate of reaction

A

How quickly a reactant is used up

How quickly a product is formed

38
Q

Average rate of reaction equation

A

Amount of reactant used or formed over time taken

39
Q

Graphs on rate of reaction

Time and amount go on what intercept

A

Time on x

Amount on y

40
Q

When is the reaction fastest

A

At the start

41
Q

The steeper the slope

A

The faster the reaction

42
Q

Collision theory

A

All particles collide with each other before a chemical reaction

43
Q

The more collisions between particles in a a given time

A

The faster the reaction

44
Q

Activation energy

A

Energy needed for chemical reactions to occur

45
Q

Four factors hat affacet the rate of chemical reaction

A

Surface area
Concentration
Temperature
Catalysts

46
Q

If the concentration of a gas or liquid increase?

A

There are more reactant particles in the same volume
More collisions per unit time
Rate of reaction increases

47
Q

Catalyst

A

Substance which speeds up a chemical reaction

48
Q
