Choose the one alternative that best completes the statement or answers the question. 1) Give the direction of the reaction, if K >> 1. A) If the temperature is raised, then the forward reaction is favored. B) If the temperature is raised, then the reverse reaction is favored. C) The forward reaction is favored. D) The reverse reaction is favored. E) Neither direction is favored. 1) 2) Express the equilibrium constant for the following reaction. CH 3 Cl(g) + 1/2 Cl 2 (g) CH 2 Cl 2 (g) + 1/2 H 2 (g) A) K = [CH 2 Cl 2 ][H 2 ] 1/2 [CH 3 Cl][Cl 2 ] 1/2 B) K = [CH 3 Cl][Cl 2 ] [CH 2 Cl 2 ][H 2 ] C) K = [CH 3 Cl] 2 [Cl 2 ] [CH 2 Cl 2 ] 2 [H 2 ] D) K = [CH 3 Cl][Cl 2 ] 1/2 [CH 2 Cl 2 ][H 2 ] 1/2 E) K = [CH 2 Cl 2 ] 2 [H 2 ] [CH 3 Cl] 2 [Cl 2 ] 2) 3) What is Δ n for the following equation in relating K c to K p ?

    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.
