Sulfur dioxide is a stable compound so its decomposition into the elements is characterized by a very small equilibrium constant.
SO2(g) ? S(s) + O2(g), K = 1.0 × 10-65 at 25oC (rxn 2)
a) Does this value apply to Kp or Kc or both? Explain.
b) Suppose a 1.0 L container is loaded with 1.0 mol SO2(g) and 0.15 mol S(s). What will be the concentrations of SO2(g) and O2(g) in the system at equilibrium? How many moles of S(s) will be found at equilibrium?
