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.
