Estimate the value of the equilibrium constant at 550 K for each of the following reactions.
1) 2CO(g)+O2(g)>2CO2(g)
2) 2H2S(g)>2H2(g)+S2(g)
i used the equation K=e^(delta G/RT) for the first problem and got K=1.40*10^49 but it was wrong. Is there a different equation i need to use?

I would try the following:
Determine delta Go at 25 C for the reaction, calculate K at 25 C, then use the van't Hoff equation to convert from K at 298 to K at 550 K.
