|Palladium crystal has 2 bond lengths, Alpha and Beta. How much energy does it take to go from alpha to beta?||
A bond between two palladium can either be in the lowest engery state called alpha and a more excited state, called beta. How much energy does it take to go from alpha to beta? Or whats the difference in the bonds engery?
2O3->3O2 deltaH=-285 kJ/molrxn
|Which reference electrode to select for electrochemical measurements? The one with Vycor or ceramic frit?||
