1) For each of the balanced equations below, write the Mass Action Expression (MAE): ( Kc and MAE are defined in section 14.2 of your text) a) H2(g)+I2(g)2HI(g) 49.4 b) N2(g)+3H2(g)2NH3(g) 4.3108 c) 2CH4(g)C2H6(g)+H2(g) d) CH3OH(g)+H2(g)CH4(g)+H2O(g)3.61020 e) H2(g)+Br2(g)2HBr(g)2.0109 2) Arrange the reactions a)-e) above, from lowest to greatest percent completion. (You may want to think about what 'percent completion' means first.) (Section 14.5) Lowest percent highest percent complete complete 3) The reaction N2O4(g)2NO2(g) has Kc=4.6103. a) What is the Kc for the reaction 2NO2(g)N2O4(g) ? (Section 14.2) b) For the reaction in a), would an increase in pressure cause the reaction to shift toward reactants, towards products, or would there be no effect? Explain, and who says so? (Section 14.6) c) In the space below, draw the Lewis structures of N2O4. (Warning! Quiz question!) Give the total (valence) electron count!!! Show all LONE PAIRS and FORMAL CHARGES
