Flashcards in 17 - 3 Deck (12):
Define rxn mechanism
A series of steps that must progress in order so that a rxn can proceed
What is a rxn mechanism also known as?
What might a rxn mechanism involve?
Describe intermediate species
Temporarily formed compounds or ions
Explain a 1 step pathway + example
Happens immediately in a single step
HCl + NaOH --> NaCl + H2O
3 step pathway ex
I2 --> 2I-
I- + H2--> H2I
I- + H2I--> 2HI
Explain rate determining step + abb
Step that will take the longest & determine overall rate & RDS
For reactions to "go" particles must...
Collide, be properly oriented & have enough nrg for valence e's to merge
Why do reactions happen?
Rxn is thermodynamically favored
Define energy of activation
Minimum initial nrg input required to transform reactants to intermediate species
What is intermediate species AKA
