Need help with this equilibrium problem
« on: October 30, 2007, 07:55:21 PM »
1) A solution of 10.0 g of NaCl in 100.0 g of water, 0 C and 1 atm
2) 100.0 g of ice at 0 C and 1 atm
Drop the ice into the solution in an adiabatic container.
a) What happens?
b) What is the final T when the system reaches equilibrium?
c) How many g of ice remain at equilibrium?

My professor has absolutely nothing like this or about this in her notes! Looked over all practice problems and tests and could not find a problem like it all.  Any insight on how to go about doing this problem would be greatly appreciated!

Thank you

I believe this is nothing more then using the fact that
Q1 + Q2 = 0
Where Q is the energy in the form of heat.
But you also have to account for the colligative property of freezing point depression.
