What experiment investigates the effect of concentration on rate of reaction?
Acid & Sodium Thiosulphate solution on paper with a cross
1 of 8
What is the formula to discover the rate of reaction?
Rate = 1 divided by :time: x 1000
2 of 8
What is an independent variable?
A variable you change in the experiment
3 of 8
What is a dependent variable?
The variable you measure of the independent variable
4 of 8
What can you conclude about concentration on rate of reaction?
As concentration increases, the rate of reaction increases
5 of 8
How can you explain the conc. x rate of reaction?
Concentrated => aka. more particles, therefore: more particles result with more successful collisions, resulting with a faster reaction
6 of 8
What are control variables?
Every other variable in the experiment, need to stay constant.
7 of 8
What experiment investigates the effect of catalysts on rate of reaction?
Side arm tube, Hydrogen Peroxide & catalyst, trough with burette that collects Oxygen
