u1: reaction mechanisms and rate law Flashcards
1
Q
mechanism
A
exact process a reaction takes
2
Q
elementary step
A
- step in reaction mechanism that involves a single collision of two or three particles (or one particle breaking down)
- all reaction mechanisms composed of elementary steps
3
Q
intermediates
A
- compounds that are produced and consumed during reaction
- appear in neither reactants or products
4
Q
rate equation for a reaction (w/ steps) depends on
A
- the slowest elementary step
- each step has diff activation energy and thus speed
5
Q
how are rate laws determined
A
experimentally
6
Q
reaction order is always defined in terms of
A
reactant concentration
7
Q
order of reactants are not related to
A
stoichiometric coefficients
