MAE 10 When the following equation is balanced using the smallest possible integers, what is the exponent of H 2 O in the reaction quotient expression? Al(s) + NaOH(aq) + H 2 O(l) <=> Na[Al(OH) 4 ](aq) + H 2 (g) Student Response Value Correct Answer 1. 6 0% Equals 0 (100%) Equals zero (100%) Score: 0/1 3. Chapter 9 Q 99 Consider the gas-phase reaction, Cl 2 (g) + Br 2 (g) <=> 2 BrCl(g), for which K p = 32 at 500 K. If the mixture is analyzed and found to contain 0.37 bar of Cl 2 , 0.37 bar of Br 2 and 2.0 bar of BrCl, describe the situation: Student Response Value Correct Answer Feedback 1. Q < K and more reactants will be made to reach equilibrium. 0%
