1.	A reaction is spontaneous if free energy change DeltaG , for the reaction is negative . The question arises, how we can explain , the spontaneous of reversible reaction taking the example of dissociation equilibrium N_2O_4 hArr 2NO_2(g) the variation of free energy with the fractionof N_2O_4 dissociated under standard conditions is shown in the figure below. The standard free energy change for the conversion of 1 mole of N_2O_4 into 2 moles of NO_2 is
Answer» 5.40 KJ `-5.40 KJ` (5.4+0.84 )KJ (5.40 +2 `XX`0.84)kJ Solution :`DeltaG=G` for 2 MOLES of `NO-2-G` for 1 moleof `N_2O_4` =5.40 kJ
