Hi
I am having toruble differentiating between the two. below the curie temperature BaTiO3 behaves as a ferroelectric, the Ti ions are offset from the centre, causing a polar domain. But it has a net polarisation is zero.
Now above the curie temperature all the dipole cancel each other out...
Thanks.
I do not understand why I don't have to use the partial pressure, when it is in the expression for Kp. Is this the case for any equilibrium constant involving kp=[x]/Po2/atm?

The equilibrium concentration of oxygen in fresh water exposed to the atmosphere is given for two temperatures. At 15 degrees celcius equilib [O2]= 630μmol/L at 25 degrees celcius equiln [O2]= 517μmol/L
The expression for the equilibrium constant, K, between the oxygen...
Thank you I figured out one and I just maked a low T approx for the second, so it is one.
Q)The bond vibrational frequencies of F2, Li2, KCl and K2 are 274 x 1011 s-1, 105 x 1011 s-1, 84 x 1011 s-1 and 27 x 1011 s-1. Considering gases of the same low density of each species, which gas would...
With regards to the rotational partition function, I narrowed it down to (1.5)^2/(1.1)^2 multiplied by e^(eob-eoa)/KbT, but I do not know the values of T so how do I complete this?
Or is that actaully part of the ratio since its the ratio multiplied by e^(eob-eoa)/KbT
You help is really really...
Number 1
For the gas phase reaction, cyclopentene + I2 = cyclopentadiene + 2HI, we find that
ln Kp = 7.55 - (4817K / T)
(where the symbol K on the right hand side refers to the units Kelvin). What are the changes in entropy and enthalpy?
Possible answers are
ΔSo = 40.05 kJK-1mol-1 and...
