Consider the following chemical reaction: 2H2(g) + O2(g) ⇌ 2H2O(g)At a certain temperature and pressure, the partial pressures of H2, O2, and H2O are found to be 0.20 atm, 0.10 atm, and 0.80 atm, respectively. Calculate the reaction quotient (Qc) for this reaction at this temperature and pressure. Is the system at equilibrium? If not, in which direction will the reaction proceed to attain equilibrium?
