Problem 14SE

The article “Enthalpies and Entropies of Transfer of Electrolytes and Ions from Water to Mixed Aqueous Organic Solvents” (G. Hefter, Y. Marcus, and W. Waghorne, Chemical Reviews, 2002:2773–2836) presents measurements of entropy and enthalpy changes for many salts under a variety of conditions. The following table presents the results for enthalpy of transfer (in kJ/mol) from water to water + methanol of NaCl (table salt) for several concentrations of methanol. Four independent measurements were made at each concentration.

a.   Is it plausible that the enthalpy is the same at all concentrations? Explain.

b.  Which pairs of concentrations, if any, can you conclude to have differing enthalpies?

Step 1 of 3

Hydrofracturing Inserts a pipe in the ground that injects water and natural gas to break up rocks for gas  Fracking has been around since 1940 and is a mature method of secondary oil recovery  Its new use as primary method of developing tight gas and shale gas formation has caused some environmental concerns  In short: its all about the water Info...
