Question : 24 of 54

Marks: +1, -0

If for an equation like N2O4(g)⇌2NO2(g), the ∆G (reaction) expression given is ∆G=4.73KJmol−1+2.5KJmol−1ℓn{‌

P2NO2

PN,o4

} then

If small amount of N2O4 is introduced in a closed container, then reaction moves in forward direction spontaneously.
Initially, ∆G∘ value is negative for the given decomposition.
At equilibrium, Qp=Kp= antilog [‌
−∆G0
RT
]
If mole fraction of N2O4> mole fraction of NO2 still reaction can be spontaneous in backword direction.
