Consider the reversible reaction shown below:

Instead of using molar concentrations, you can use gas pressures to calculate an equilibrium constant, in which case it is often labeled K_p instead of K_eq. For this reaction, K_p = 3.40 atm^–1 at 1000 k. Consider a flask filled with all three of these gases such that p_SO2 = 0.48 atm, p_O2 = 0.18 atm, and p_SO3 = 0.72 atm. Is this reaction at equilibrium or not? If not, which way will it shift to get there?
