Reaction kinetics Flashcards
1
Q
Rate of reaction equation?
A
ROR=-1/a(delta A/delta t) = -1/b(delta B/delta t) = 1/c(delta C/delta t) = 1/d(delta D/delta t) =
2
Q
rate laws
A
rate=k[A]
3
Q
what is rate constant based on
A
what reaction
reaction conditions
reaction order
4
Q
describe zero order kinetics and k units?
A
conc increases but ROR doesnt change.
rate: mol L-1 s-1
5
Q
describe first order kinetics and k units
A
as conc increases, ROR increases linearly
rate: s-1
6
Q
describe secod order kinetics and k units
A
as conc increases, ROR increases by factor of 2
rate: L mol-1 s-1
7
Q
rate order for multiple reactants?
A
add rate constants
8
Q
for radioactive decay, how long is each half life
A
they are identical in cength
9
Q
2 ways of determining rate laws?
A
- method of initial rates
- > given initial rates, concs and conc’s at different RATES. infer it
- integrated rate laws
- > not given initial rates; only conc’s at different TIMES
