rate determining step Flashcards
1
Q
what is the rate determining step?
A
slowest step in a mechanism which determines the rate of reaction
2
Q
how do the rate equation and RDS link?
A
substances in the rate equation must be involved in the RDS
3
Q
NO2 + CO –> NO + CO2
rate = k[NO2]2
A
RDS = NO2 + NO2 –> NO + NO3
fast step = CO + NO3 –> CO2 + NO2
4
Q
what does it mean if a species is a catalyst?
A
used and regenerated
5
Q
what does it mean if a species is an intermediate?
A
formed and used
6
Q
what substances need to be in the rate determining step?
A
everything in the rate equation
