Thermodynamics and Kinetics Lecture 31 Notes: Kinetics

The class average on the recent test was 57 +/- 17 points with a high of 85.

Today’s lecture costs 46 minutes of your time.


2nd order rxns come in two flavors:
A+A = products
A+B = products
1/A = kt + 1/Ao
y = mx + b

dA/dt = kAB
x = Ao-A
dx/dt = -dA/dt
x = Bo-B
dx/dt = k(Ao-x)(Bo-x)
kt = 1/(Ao-Bo) ln(ABo/AoB)

if Ao=Bo,
1/A = kt + 1/Ao

if Ao>>Bo,
k’ = kAo

Things can get complicated. To prevent this, flood the system to make it look like a 1 component system.

Solving A+B+C = product

1) Initial Rate Methos
-dA/dt at to = Ro
replace with Ao’=Ro’

2) Flooding/Isolation
Ao << Boto
dA/dt = k A^a Bo^b Co^c

Then's its all just a matter of finding mechanisms.

Molecularity is the number of molecules that need to colide. Above it 3. One molecule, 1st order rxn. 3 molecules, 3rd order.

3rd order reactions are quite rare and need to be highly concentrated.

A = B + C
-dA/dt = k1A + k2A
dB/dt = k1A
dC/dt = k2A

oh my such great apple pie: oxalic malonic succinic glutaric adipic paleric.
Tooth: enamel, dentis, pulp

Op Amp
Non Inverting G = Vo/Vi = 1+Rf/Ro
Inverting G = -Rf/Ro

BLISS blend low irregular small secluded
LACE liquid ammo casualties equipment
METTTC mission enemy troops terrain time civilians
SPLC staffing probabilities logistics contingencies

1st Law dU = dQ + dW
2nd Law dS = dQ rev/T
3rd Law OK, s=0

Add acid to water, not water to acid

u = G/n
