reaction rates Flashcards
1
Q
how can the reaction speed be measured
A
- the speed the reactants are used up
- the speed products are formed
2
Q
what units can reaction rates be measured in
A
mass (grams)/second
volume (mL)/second
3
Q
reaction rate equations
A
Reaction rate = quantity of reactant used up
time
Reaction rate = quantity of product formed
time
4
Q
solids can be measured by
A
mass
5
Q
gases can be measured by
A
volume
6
Q
why are aqueous solutions harder to monitor
A
because they dont change mass or volume
7
Q
when are gas syringes used
A
when reactions produce gas
8
Q
why are gas syringes better for gas volume
A
because they are easier to use and are more accurate
