Question

1) Which reaction will shift to the left in response to a decrease in volume? A) 2 SO3 (8) 2 SO2(g) + O2(8) B) N2(g) + 3H2(g) + 2NH3(g) C) 2H1 (8) H2(g) + 12 (8) D) 4 Fe (8) +32(g) 2 Fe2O3 (s) E) H2 (8) + Cl2(g) 2 HCl (g) Explain 2) Based on Le Châtelier's principle, increasing pressure at constant temperature in the following reaction will not change the concentrations of reactants and products. A) N2 (8) +202 (8) 2NO2 (8) B) N2(g) + O2(g) 2NO(g) C) 2N2 (g) + O2(g) 2N20 (8) D) N204 (8) 2N02 (8) E) N2 (g) + 3H2 (8) 2NH3 (8) Explain

) ) ) Decrease in volume will shift shift reaction to left in that case where number of gaseous molemles are less in the reactant side. Only one that is option optain option (A) has less gaseus molecules in the reactant side... Option ® is the correct option. 25030 = (mol) 2500 a + O20 - Increase in presure at constant temperature implies decrease in volume. Reaction having same number of notes reactant molecules of gas will have no effect of de both change in volume. Only one option, that is option B has equal molecules of gas on both sides. a. option B is the correct option. 3mol ) E LTL11111211
