L14&15 - reaction kinetics Flashcards
1
Q
what affects the rate of reaction
A
temperature
reactant concentration
catalyst
2
Q
initial rate eqaution
A
rate = k[A]^x
where:
k = rate constant
x = reaction order
3
Q
what types of reactions are zero order
A
mostly catalysed reactions
4
Q
order method 1
A
make [B]»_space; [A]
log rate = logk + x log[A] (linear equation)
plot graph and gradient = order
5
Q
what kinetic plot creates a linear (-K) slope for a 0 order reaction
A
[A] vs T
6
Q
what kinetic plot creates a linear (-K) slope for a 1 order reaction
A
ln[A] vs t
7
Q
what kinetic plot creates a linear (k) slope for 2 order reaction
A
1/[A] vs t
8
Q
what is the rate determining step
A
slowest: formation of transition state
