17.66 The "filmstrip" represents five molecular scenes of a gas- eous mixture as it reaches equilibrium over time: A в D E X is purple and Y is orange: X,(g) + Y,(g) = 2XY(g). (a) Write the reaction quotient, Q, for this reaction. (b) If each particle represents 0.1 mol, find Q for each scene. (c) If K> 1, is time progressing to the right or to the left? Explain. (d) Calculate K at this temperature. (e) If AHn < 0, which scene, if any, best represents the mixture at a higher temperature? Explain. (f) Which scene, if any, best represents the mixture at a higher pressure (lower volume)? Explain. rxn
