Multiple-choice questions may continue on the next column or page find all choices before answering. 001 2.0 points For the reaction CO(g) + 2 H 2 (g) CH 3 OH(g) G rxn = 21 . 1 kJ/mol at 225 C. If you have a mixture with a P CO = 0 . 1 atm, P H 2 = 0 . 1 atm, and P CH 3 OH = 1 atm in a container at 225 C, 1. the mixture can never achieve equilib- rium. 2. the reaction will move toward the reac- tants to reach equilibrium. correct 3. the reaction is at equilibrium. 4. the reaction will move toward the prod- ucts to reach equilibrium. Explanation: G rxn > 0, so K < 1 and Q = 1000. Q > K , so the reaction will shift toward the reactants to reach equilibrium. 002 2.0 points Consider the reaction: S( s ) + 3 F 2 ( g ) SF 6 ( g ) If K = 10 3 and 0.1 mol of each species is added to a 1 L container, what will occur?...
