ThevariationoffreeenergywiththefractionofN2O4dissociatedunderstandardconditions is shown in the figure below:
Thestandardfreeenergychangefortheconversionof1moleofN2O4into2molesofNO2is:
- 5.40kJ
- —5.40kJ
- (5.40 +0.84)kJ
The correct answer is: 5.40kJ
DG = G for 2 moles of NO2- G for 1 mole of N2O4 . = 5.40 kJ Hence, (a) is the correct answer.

Electronegativity is a feature which is relative and depends on several factor like oxidation number, hybridizations etc.
For instance, the electronegativity of differently hybridized carbon are :
ThedirectionofdipoleofC→0 is This means there is slight positive charge on O. This can be explained by:
