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 0.55 bar of Cl 2 , 0.65 bar of Br 2 and 3.3 bar of BrCl, describe the situation: Student Response Value Correct Answer Feedback 1.

### What students are saying

• 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.
