Measuring Rates Of Reaction

Question 1

What are the two ways to calculate rate of reaction?

Answer 1

          Time Taken

           Time Taken

Question 2

What are all ways to measure rate of reaction?

Answer 2

Change in mass Volume of gas
———————— ———————
Time Time

                          1
                     -----------
                        Time

Question 3

How does a change in mass and time graph look like and what is always the X axis?

Answer 3

Going down slowly, until it’s constants as no more reaction occurs

Time

Question 4

How does a volume and time graph look like?

Answer 4

The opposite to the change in mass one

Question 5

How do you measure volume of grass produced?

Answer 5

Gas of the reaction displaces the water in the cylinder pulling it down

Question 6

What are pros and cons of using gas syringe instead of measuring cylinder?

Answer 6

Pros=useful for soluble gases, more accurate
Cons=often leaks

Question 7

How does the disappearing cross method?

Answer 7

Precipitate (solid formed) makes reaction go cloudy
