Type 3 20 In the reaction below, 2 atm of H 2 and 2 atm of Cl 2 were placed into a 1.00 L flask and allowed to react: H 2 (g) + Cl 2 (g) <=> 2 HCl(g) Given that Kp at 800 K is K = 36, calculate the equilibrium pressure of HCl. Student Response Value Correct Answer Answer 3 100% 3.00 Score: 1/1 2. Type 3 11 In the reaction below, 3.82 atm each of H 2 and Br 2 were placed into a 1.00 L flask and allowed to react: H 2 (g) + Br 2 (g) <=> 2 HBr(g) Given that Kc = 70.0, calculate the equilibrium pressure of H 2 . Student Response Value Correct Answer Answer .737 100% 0.74 Score: 1/1 3. Combining Equations 1 In combustion studies of the use of H 2 at an alternative fuel, HO is sometimes formed in flames by the reaction, H(g) + 1/2 O 2 (g) <=> HO(g) Use the data below to calculate the value of K c H 2 (g) <=> 2 H(g) K c = 0.00861 1/2 H 2 (g) + 1/2 O 2 (g) <=> OH K c = 0.397

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
