Question 1

Pauli principle

Answer 1

wavefunction must be antisymmetric on interchange of electron coordinates

Question 2

Pauli exclusion principle

Answer 2

No 2 electrons can occupy the same spin orbital

Question 3

gross and selection rules for
Pure rotational spectroscopy

Answer 3

the molecule must be polar
Delta J = ±1

Question 4

gross and selection rules for
Infrared absorption spectroscopy

Answer 4

the dipole moment of the molecule changes during thr vibration
Delta v = ±1

Question 5

gross and selection rules for
Vibrational raman spectroscopy

Answer 5

the polarisability of the molecule changes during the vibration
delta v = ±1

Question 6

zero order differential and integrated form

Answer 6

-d[A]/dt = k
[A] = [A]₀ - kt

Question 7

first order differential and integrated form

Answer 7

-d[A]/dt = k[A]
ln[A] = ln[A]₀ - kt

Question 8

second order differential and integrated form

Answer 8

-d[A]/dt = k[A]^2
1/[A] = 1/[A]₀ + kt

Question 9

clausius clapeyron

Answer 9

ln(pvap,1/pvap,2) = delta vapH/R (1/T2 - 1/T1)
