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 1.2 bar of Cl 2 , 1.6 bar of Br 2 and 7.9 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% 2. Q < K and more products will be made to reach equilibrium. 0% 3. Q > K and more reactants will be made to reach equilibrium. 100% 4. Q > K and more products will be made to reach equilibrium. 0% 5. Within 1 decimal place, Q = K and the reaction is at equilibrium 0% View Attempt https://scholar.uh.edu/webct/urw/lc305051878.tp305053160/ViewStudent. .. 1 of 8 27-Oct-09 2:22 AM

Score: 1/1 2. At a given temperature, Kp for the reaction below is 0.24. In a given experiment, 0.10 atm of each product and 0.0020 atm of NOBr are intoduced into a container. In which direction will the reaction proceed, or is it at equilibrium? 2 NOBr(g) <=> 2 NO(g) + Br 2 (g) Student Response Value Correct Answer Feedback 1. Reaction will go to the left 100% 2. Reaction will go to the right 0% 3. Reaction is an equilibrium 0% Score: 1/1 3. At a certain temperature, K p for the reaction, H 2 (g) + Br 2 (g) <=> 2 HBr(g) is 0.00738. Calculate the value of K p for the reaction, HBr(g) <=> 1/2 H 2 (g) + 1/2 Br 2 (g) Student Response Value Correct Answer Answer 11.6 100% 12 Score: 1/1 4. Calculate K
