Measuring Rates Of Reaction

Question 1

What are the equations for RoR?

Answer 1

quantity of reactant used/time taken

quantity of product formed/time taken

Question 2

How can we find out the quantity of reactant used up?

Answer 2

Change in mass

Question 3

How can we measure the quantity of product formed?

Answer 3

Measuring volume of gas produced

Question 4

How can we measure gas produced?

Answer 4

• gas syringe

- upside down measuring cylinder

Question 5

Why does a RoR graph plateau?

Answer 5

Reactants get used up

Question 6

How can you measure colour change?

Answer 6

• conical flask on top of drawn cross
• as reaction progresses, more solid forms & solution turns cloudy
• cross no longer visible
• time how long it takes for solution to turn cloudy
