For the same reaction, the standard Gibbs
energy of reaction at 2000K is +135.2 kJmol−1
. Suppose that
steam at 200 kPa is passed through a furnace tube at that
temperature. Calculate the mole fraction of O2 present in the
output gas stream.
i cant find the right result

Show what you did so far and why you think the answer is incorrect.

The standard Gibbs energy of reaction for the decomposition of water
H2O(g) --> H2(g) + 1/2 O2(g)
is 135.2 kJ/mol at 2000K. Suppose that steam at 200 kPa is passed through a furnace tube at 2000K. Calculate the mole fraction of H2(g) in the output gas stream.
sorry, the full question is like that.
First I found k=(p/Po)^1/2* alpha3/2 / 2^1/2 ( 1 - alpha )
using ice table and k value using delta G=RTlnk but I can not understand where should I put the given pressure

You didn't forget the minus in ΔG° = -RTlnK, did you?
