If you plug in 298 for T you will get Kp at 298. Then the van't Hoff equation will convert that to K at 740K.
ln(kt2/kt1) = dHo(1/T1-1/T2)/R
A possible reaction for converting methanol to ethanol is
CO(g)+2H2(g)+CH3OH(g)→C2H5OH(g)+H2O(g)
ΔH0 for this reaction at 25∘C.
ΔH0 = -165.7 kJ
ΔS0 for this reaction at 25∘C.
ΔS0 = -227.4 J/K
ΔG0 for this reaction at 25∘C.
ΔG0 = -97.9 kJ
- Estimate Kp for the reaction at 740 K .
Express your answer using two significant figures.
what i did
(-97.9kJ)(1000) = -(8.314)(740K) lnK
-97900 / -(8.314)(740K) = ln K
e^(-97900 / -(8.314)(740K)) = K
Kp = 8.1x10^6
The above answer is not correct. Plz help. Thanks
