Rate equation?
r=k[A]^x[B]^y
1 of 10
How do you work out the overall order of a reaction?
Add all the powers together
2 of 10
What is the rate of a reaction?
The change in concentration of reactants per unit time.
3 of 10
What happens when a reactant is 1st order?
the change in the rate is the same as the change in concentration
4 of 10
What happens when a reactant is 2nd order?
the change in the rate is the change in concentration squared
5 of 10
What happens when a reactant is 0 order?
the change in concentration has no effect on the rate change
6 of 10
Which step is the rate determining step?
the slowest step in a chemical reaction
7 of 10
When there is an increase in temperature..
..k increases.
8 of 10
When there is a decrease in temperature..
..k decreases.
9 of 10
If the concentration or pressure is changed at a constant temperature..
..k will not change.
