Consider the following equilibrium:

N2O4(g) <--> 2NO2(g)

We can assume the heat of formation and standard change in entropy do not vary with temperature.

At what temperature will an equilibrium mixture contain equal amounts of the two gases?

where G = standard free energy change

-G/(R*ln(K(eq))) = T

delta G = delta H - T*(delta S)

There's two unknowns K(eq) and T. How do i figure out the value of K(eq) to solve this problem? Like, is there some sort of relationship of the K(eq) when both the gases are at the same amount?

K(eq) = X^2/X = X <---- this will become a variable, so how can i determine the K(eq).

Please help. Thanks in advance....
