Calculate the work done when 70.0g of tin dissolves in excess acid at 3.00 atm and -15.0 C.
Sn(s)+2H^+(aq) -> Sn^2+(aq)+H2(g)
Assume ideal gas behavior.
Any ideas? I've come up with a few different answers and can't come to a conclusion.
I see the following energies involved:
1) tHe ionization energy of Sn
2) the ionization energy of H+
3) the energy of formation of H2(g)
On 1) make certain the data reflects solid to aq. All of those ought to be standard table look ups. I don't have my Merck or CRC handy.
