What happens to reaction rate as the concentration of reactants increases?

Rate increases

What precipitate forms when sodium thiosulfate reacts with hydrochloric acid?

Sulfur

Why is sulfur precipitation useful for this experiment?

It doesn't dissolve in water

What is placed under the conical flask during the experiment?

White paper with a cross

When should you stop timing in this experiment?

When the cross can't be seen

Which variable should be changed to make this a fair test?

Conc. of sodium thiosulfate only

What formula is used to calculate reaction rate?

Rate=1Time\text{Rate} = \frac{1}{\text{Time}}

If a reaction takes 20 seconds, what is the rate in sec−1\text{sec}^{-1}?

0.05

What relationship does the time vs concentration graph show?

Inverse (curved line)

What does a rate vs concentration graph look like?

Straight line through origin

If you double the concentration, what happens to the reaction rate?

Rate doubles

According to collision theory, why does higher concentration increase rate?

More particles = more collisions

Why should the same observer judge when the cross disappears?

To reduce human error
