Thermodynamics and Kinetics Lecture 31 Notes: Kinetics

Overview
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’
Ro/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.

A+B+C=D+E
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

Review
oh my such great apple pie: oxalic malonic succinic glutaric adipic paleric.
G=H-TS=-RTlnK=-nFE
Tooth: enamel, dentis, pulp

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

sight alignment, sight picture, trigger control
BRASS breathe relax aim sight shoot
BRASS breathe relax aim slack squeeze
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

Sensory Layer: fovea, macula, peripheral

Add acid to water, not water to acid

u = G/n
Polymerization: condensation/radical
