Chem 2B: more equilibrium fun! Clemens 1. A flask at 298 K contains 0.500 atm of N 2 O 4 and 0.500 atm of NO. After reaching equilibrium, the partial pressure of N 2 O 4 is 0.600 atm. What is the total pressure at equilibrium? Find K p and K c . N 2 O 4 (g)  2 NO 2 (g) 2. AT 80 o C, K p = 1.57 for the following, PH 3 BCl 3 (s)  PH 3 (g) + BCl 3 (g) Calculate the equililbrium partial pressures of PH 3 and BCl 3 if a sample of PH 3 BCl 3 is placed in a closed vessel at 80 o C and allowed to demcompose.

Unformatted text preview: 3. If 1.2x10-3 M HBr is allowed to react at 500K, what is the percentage of decomposition of HBr and what is the equilibrium composition of each reactant and product? 2HBr (g) H 2 (g) + Br 2 (g) K = 7.7x10-11 at 500K 4. 0.0240 moles of N 2 O 4 is allowed to come to equilibrium with NO 2 in a 0.372L flask at 25 o C. What is the equilibrium concentration of each at room temperature? N 2 O 4 (g) 2 NO 2 (g) K = 4.61x10-3 at 25 o C,...

    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.
