Another 2 mol SO2 is added to the system. Assume the temperature and volume are kept constant. 3. (a) What happens to the pressure in the system? (b) Suggest the new value of the partial pressure of SO2 in the system before any shift in the position of equilibrium. (c) What has happened to the partial pressures of O2 and SO3? We will now introduce you to the reaction quotient, Q. Q can help you predict how an equilibrium will shift if you disturb it, for example by adding more of one of the components. Q is calculated using the same expression as Kp, but you insert the partial pressures immediately after the equilibrium has been disturbed before the equilibrium has settled to accommodate the change. – 4. (a) Using the partial pressures from question 3 and the expression for calculate for the Kp, Q system after addition of 2 mol SO2.
