Question
TABLE 2-2 Thermodynamic Changes for Transferring Hydrocarbons from Water to Nonpolar Solvents at 25 c AH kJ mol- 11.7 -TAS kJ mol -22.6 AG (kJ mol- -10.9 Process 5. Based on math, would you say the process is driven by enthalpy or entropy? ("Driven" meaning the G's sign and magnitude is mainly due to the component given.) During the net transfer of methane from water to benzene, do the interactions within the system become stronger or weaker? Give your evidence for your conclusion. 6. 7. During the net transfer of methane from water to benzene, does the disorder of the system increase or decrease? 8. Based on your prior knowledge, would you say this transfer demonstrates the hydrophobic effect? Explain (1-2 sentences)Explanation / Answer
5)it is entropy driven
If the change in entropy S is positive and large enough to make G < 0 (when H > 0), then the reaction proceeds in forwarding direction just because of positive entropy change and then the reaction is called entropy-driven reaction.
6)stronger
7)since the change in entropy S is positive, the disorder of the system increases
8)methane is transfered from water to benzene ,since methane is non polar this can demonstrates hydrophobic effect
