hey i seem to be having a lot of trouble qith this question may i get some help?
The standard potential of the cell below is + 0.9509 V at 25 oC. Calculate the solubility, normally called s, of AgI (Note: Enter the natural log of s (ln s) as your answer)
Ag|AgI(s)|AgI(aq)|Ag
i'm using nernst...
would anyone happen to know what the expression for an isothermal change in Gibbs free energy for a liquid is when the pressure changes from pi to pf. Also an expression for when its a perfect gas?
i can't seem to figure them out.. and how would they be deduced?
i've come across one equation...
ethanol 46g/mol freezes at 3.65degC density changes from 0.789g/cm-3 to 0.801g/cm-3 latent hear of fusion 8.68kJ/mol. freezing point at 1000 atm.
i calculated the ansfer from an example and just want to verify if its correct.
dp/dt=(dfusH)/(t*dfusV) rearanged to dt=(dp*t*dfusV)/dfusH...
hey, i was wondering if anyone could help with this question. it seems simple but i can't find a formula for it.
2.5 mol of perfect gas at 220 K and 200 kPa is compressed reversibly and adiabatically until the temperature reaches 255 K. Given that its molar constant-volume heat capacity, CV,m...
hey all,
i'd just like to say thanks for attempting to help or just even having a browse.
i have 5 questions in which i have some idea about but still very hard to produce an answer.
1:
What is the difference in boiling point of water between sea level (p = 1 atm) and on top of a mountain...
hey I'm going through an exam paper and I'm having a difficult time working them out. any help will be greatly appreciated. thanks!
the first question is for the size of an atom..
The second virial coefficient, B, at high temperatures equals half the excluded volume due to the repulsive part...
thanks man
Thanks heeeeeeeeeaps! Daniel :biggrin:
you made my day. spent ages doing that Q like hours and hours just seraching what i was doing wrong. thanks again.
this forum rOcks!

hey i seem to be having a lot of trouble with this type of question:
Calculate the change in Gibbs energy of 35g of ethanol (mass density = 0.789g cm-3) when the pressure is increased isothermally from 1 atm to 3000 atm.
in my notes i have that dG=V(Pf-Pi) and search up on the net that...
