1. Is the dissolution process studied today, NaNO3( s)→Na+(aq)+NO3−(aq)
Using the class's mean value for ΔH, and the Gibbs-Helmholtz equation, estimate the value for ΔS for the dissolution process. (See Calculations section.) ΔH=38.17 K⋅Imal 3. Based on your observation about the spontaneity of the reaction and the sign of ΔH, is the value of ΔS that you calculated a minimum or a maximum? Explain. ΔS=T−ΔH 4. Looking at the chemical equation above, would you predict that the sign of ΔS for the dissolution process is positive or negative? Explain.
