18.1 Orders and rate constants Flashcards
1
Q
what is the rate?
A
change in concentration over time
2
Q
zero order reaction
A
to the power of 0
concentration has no effect on the rate
3
Q
first order reaction
A
to the power of 1
increasing conc by 2 will increase rate by 2
increasing conc by 3 will increase rate by 3
etc
4
