this topic is very hardd!
need help on this qn
Standard Enthalpy change of Formation of NaCl -414
Lattice Energy of NaCl -779
Hydration energy of gaseous sodium ions -390
Hydration energy of gaseous chloride ions -384
Standard enthalpy change of formation of aq NaCl -409
how to draw 2 different energy level diagrams to obtain 2 values for the enthalpy change of solution?
Haha. One energy level cycle is Nacl (s) --> Nacl(aq)
Nacl(g)
2nd energy cycle requires you to have enthalpy change of atomisation ,
Na(s) + 1/2 cl2(g) ---> Nacl(aq)
Nacl(g)
hmmm ya. but how to draw on the energy level diagram the one that kind of looks like a graph? i read all the guidebooks for help, but all is those Ionic solids kind.
