In Problem 4A, you are given initial concentrations and asked which direction the reaction will go.  This involves formulating the reaction quotient, Q and comparing it to the equilibrium constant, K.  If Q is smaller than K, the reaction will go forward.  If it is greater than K, the reaction will go in reverse.  This is what I call the “easy” version of a Type 5 problem – determining the direction.    Problem 4B asks what the concentrations will be at equilibrium.  This is a harder problem and it involves setting up the ICE chart and solving it.  I refer to this as the “hard” version of a Type 5 problem – determining not just the direction but what the concentrations are at equilibrium.  You will have to come back to this part of the problem when we have covered how to solve it.   4A)  Suppose you place some solid NH4HS in a flask containing 0.50 atm NH3 (g).  Which way will the reaction go?  (Given:  Kp = 0.11.)   NH4HS (s)              H2S(g)     +     NH3 (g)…

Calculate the equilibrium concentration of NOCl in the reaction: 2NO(g) + Cl2(g) ↔ 2 NOCl(g) Kc = 4.601 x 104[NO] = 0.300 M[Cl2] = 0.500 M

63) A student mixes two solutions: 10.0 mL of 0.0040 mol/L lead (II) nitrate, Pb(NO3)2 (aq), and 15.0 mL of 0.25 mol/L potassium chloride, KCI (aq). If the solubility product constant, Ksp, for lead (II) chloride, PbC12, is 1.2 x 105 at 25 °C, will a precipitate from when these two solutions are mixed? Why? ne bronsied - LoWry theory, Dut no

Consider the reversible dissolution of lead(II) chloride. PbCl (s) Pb²+ (aq) + 2 Cl (aq) Suppose you add 0.2460 g of PbCl, (s) to 50.0 mL of water. When the solution reaches equilibrium, you find that the concentration of Pb+ (aq) is 0.0159 M and the concentration of Cl (ag) is 0.0318 M. What is the value of the equilibrium constant, K. for the dissolution of PbCl, ?
