1.  (Points: 4)    c.  the reaction will proceed in the direction that results in fewer gas phase particles. d.  the reaction will proceed to the right until equilibrium is established. e.  the reaction will proceed to the left until equilibrium is established.   5.  (Points: 4)      A 4.00 L flask is filled with 0.75 mol SO 3 , 2.50 mol SO 2 , and 1.30 mol O 2 , and allowed to reach equilibrium. Predict the effect on the concentrations of SO 3 as equilibrium is achieved by using Q , the reaction quotient. Assume the temperature of the mixture is chosen so that K c = 12. 2 SO 3 (g) 2 SO 2 (g) + O 2 (g) a.  [SO 3 ] will decrease because Q > K . b.  [SO 3 ] will decrease because Q < K . c.  [SO 3 ] will increase because Q < K . d.  [SO 3 ] will increase because Q > K . e.  [SO 3 ] will remain the same because Q = K .   Save Answer
