1 1 Which statement about the production of ammonia, NH 3 , from N 2 and H 2 is not correct? A) Converting N 2 into ammonia is problematic because of the high activation energy due to the strong N-N triple bond. B) High pressures in the reactor favor the formation of ammonia consistent with LeChatelier’s principal. C) High temperatures are used because the reaction is endothermic and entropy driven so the equilibrium constant is larger at high T. D) Bacteria associated with some plants readily convert N 2 into ammonia using enzyme catalysis. 2 Homework POGIL-IC Problem The Composition of the Dead Sea Also complete the survey By Sunday, March 9, 3 AM Both on BB in Assignments Section Basis for LUCID quiz Out today, due Sunday, March 9, 3 AM

2 3 Solubility Product Constant & Concentration Product Ag 2 SO 4 (s) 2 Ag + (aq) + SO 4 2- (aq) Solubility product constant, K sp K sp = [Ag] 2 [SO 4 2- ] Involves the equilibrium concentrations Concentration product, Q sp Q sp = [Ag] 2 [SO 4 2- ] Involves the concentrations whether or not at equilibrium. 4 Solubility Product Constant, K sp Like QRT 14.39. Silver sulfate (K sp = 1.7 x 10 -5 ) and silver chloride (K sp = 1.8 x 10 -10 ) are not very soluble in water. 1. Write the reaction equations describing the dissociation of each of these salts when they dissolve in water.

### 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.
