What is the rate-determining step (RDS)?
What is the rate-determining step (RDS)?
Slowest step that controls overall reaction rate
How does RDS affect overall reaction?
How does RDS affect overall reaction?
It's the slowest, limits speed of entire reaction
Which species appear in rate equation?
Which species appear in rate equation?
Those involved in RDS with non-zero orders
Zero order reactants in RDS
Zero order reactants in RDS
Do not participate in the rate-determining step
