K+ (aq) +
NO3-(aq
Determine the thermodynamic variables, ΔG, ΔH, and ΔS, for the
dissolving of KNO3 in water. You will find these
variables by creating a Van’T Plot, which is a graph of
lnK(sp) vs 1/T.
A set amount of KNO3 is weighed and dissolved in 25mL
of water and heated until all the KNO3 is
dissolved....
