Rates Of Reaction 1

Question 1

What’s step 1 of 1st experiment?

Answer 1

Choose the size of marble chips and weigh them on a scale before putting them in the conical flask

Question 2

What’s step 2 of 1st experiment?

Answer 2

Record the acid concentration and add it to the marble chips and time it using a stop watch.

Question 3

What’s step 3 of 1st experiment?

Answer 3

Record time and the volume of gas produced.

Question 4

What’s step 4 of 1st experiment?

Answer 4

Change the reaction time and repeat experiment to obtain a series of values of volume of gas and time.

Question 5

What’s step 5 of 1st experiment?

Answer 5

Repeat the whole experiment using different sized marble chips.

Question 6

How do you find the rate of reaction in experiment 2?

Answer 6

By measuring the volume of gas collected in 1 minute for different acid concentrations.

Question 7

What’s step 1 for 2nd experiment?

Answer 7

Run the reaction and record the final volume of gas

Question 8

What’s step 2 for 2nd experiment?

Answer 8

Repeat the experiment for different acid concentrations

Question 9

What’s the aim?

Answer 9

To see how the rate of the reaction depends on the concentration of the acid and the size of the marble chips used.
