Question

1. The standard Gibbs free energy for iodine sublimation, I2(s) --> I2(g), ?Go = + 19.4 kJ/mol. Explain why solid iodine sublimes in open air at 298 K

2. Demonstrate that to transfer heat from a source of lower temperature to a body of higher temperature violates the 2nd law of thermodynamics and is therefore not possible without additional work.

And if you're feeling nice (please >.<)...

3.What reactions take place at the electrodes when you "recharge" a lithium ion battery?  What might limit the battery from being "fully" recharged?  Describe what changes to the chemistry might occur after an initial discharge.

Thanks in advance!

Explanation / Answer

1) ?G= ?Go +RTlnk

by this we will get ?G value negative which implies reaction is spontaneous

2)"It is not possible to transfer heat from a source of lower temperature to a body of higher temperature" is one of the statements for second law of thermodynamics which explains the second answer

3)saltbridge might limit the battery from being "fully" recharged .
