Kinetics Flashcards
1
Q
Rate of reaction at any instant
A
Rate = a/b = change in conc./time
2
Q
The rate expression
A
Tell us about the contributions of the species that do affect the reaction rate.
X + Y -> Z
4
Q
Units for 0 order reaction
A
Rate = k
Units - mol dm-3 s-1
5
Q
Units first order reaction
A
Rate = k[A]
k = rate/[A]
Units - s-1
6
Q
Units second order reaction
A
Rate = k[B][C]
K
k = rate/[B][C]
Units = mol-1 dm3 s-1
7
Q
Units third order reaction
A
Rate = k[D][E]2
k= rate/[D][E]2
Units - mol-2dm-3 s-1
8
Q
lnk
A
-Ea/RT
lnk=lnA
9
Q
Ea
A
Ea = lnA - lnk (RT)
10
Q
T
A
T = Ea/lnA-(lnk x R)
11
Q
lnA
A
Ea/RT
lnA = lnk
