Thermodynamics and Kinetics Lecture 12 Notes

Overview
Today’s lecture is 48 minutes long. Looks like this teacher uses soft drinks.

For spontaneous change, we need dS>0.

The Clausius Inequality
dS > dq/T surr

2H2O2 = 2H2O O
dH = -201 kJ
dS = + 132 J/K

G = H – TS = -RT ln K

Equilibrium under different conditions:
1) An isolated system where q=w=- and dU = 0, dw=0

3H2 +N2 = 2NH3
dH = -92 kJ
dS = -198 J/K

NaCl + H2O = Na+ + Cl- + H2O
dH = + 4 kJ
dS = -45 J/K

Equilibrium is when the forward and reverse rates are equal. No spontaneous changes can occur.

1st law dU = dq + dW
2nd law dS > dq/T surr
dU <TdS – pdV

dU + pdV -TdS < 0
all are state functions.

For an isolated system to react, the entropy must increase.

For constant S and V systems, the equilibrium has the lowest PE available. The entropy of a mixed gas. Maxiimize the number of configurrations.

For constant S and P processes, the equilibrium state is the state with the lowest H.

For systems with T=T surroundings, and constant V, A = U-TS Helmholz free energy

constant T and P, G = U + pv -TS

Mandatory Refusal – when communications are lost, no one is trusted. A breach is assumed.

CARVER is an acronym that stands for Criticality, Accessibility, Recuperability, Vulnerability, Effect and Recognizability.

Wind Speed Beaufort Category How to Judge the Wind
1-3 mph Light Air Smoke drifts. Wind cannot be felt.
4-7 mph Light Breeze Wind felt on face. Leaves rustle. Weather vanes move.
8-12 mph Gentle Breeze Leaves and twigs in motion. Light flags are extended.
13-18 mph Moderate Breeze Wind raises dust and loose papers. Small branches move. Flags flap.
19-24 mph Fresh Breeze Small trees in leaf sway slightly. Wavelets form on ponds and lakes.
25-31 mph Strong Breeze Large branches move. Telephone lines sing.

Visible Light – 400 to 700 nm
