Determine the value of the equilibrium constant (Kp) at 800. K and 1 atm pressure.

SbCl3(g) + Cl2(g) -> SbCl5(g)

Delta G(o)f (SbCl5) = -334.34 kJ/mol
Delta G(o)f (SbCl3) = -301.25 kJ/mol
Delta H(o)f (SbCl5) = -394.34 kJ/mol
Delta H(o)f (SbCl3) = -313.80 kJ/mol

I got a K value of 1.14 x 10^3, am I right?

I can't confirm that. Will you post your work?
