Answer to relevant QuestionsWrite expressions for K and Kp for the following reactions. a. 2NH3(g) + CO2(g) ⇌ N2CH4O(s) + H2O(g) b. 2NBr3(s) ⇌ N2(g) + 3Br2(g) c. 2KClO3(s) ⇌ 2KCl(s) + 3O2(g) d. CuO(s) + H2(g) ⇌ Cu(l) + H2O(g) For the reaction H2(g) + Br2(g) ⇌ 2HBr(g) Kp = 3.5 × 104 at 1495 K. What is the value of Kp for the following reactions at 1495 K? a. HBr(g) ⇌ 1/2 H2(g) + 1/2 Br2(g) b. 2HBr(g) ⇌ H2(g) + Br2(g) c. 1/2H2(g) + 1/2 ...A sample of gaseous PCl5 was introduced into an evacuated flask so that the pressure of pure PCl5 would be 0.50 atm at 523 K. However, PCl5 decomposes to gaseous PCl3 and Cl2, and the actual pressure in the flask was found ...At 25oC, K = 0.090 for the reaction H2O(g) + Cl2O(g) ⇌ 2HOCl(g) Calculate the concentrations of all species at equilibrium for each of the following cases. a. 1.0 g of H2O and 2.0 g of Cl2O are mixed in a 1.0- L flask. b. ...At 25oC, Kp = 2.9 × 10-3 for the reaction NH4OCONH2(s) ⇌ 2NH3(g) + CO2(g) In an experiment carried out at 25oC, a certain amount of NH4OCONH2 is placed in an evacuated rigid container and allowed to come to equilibrium. ...
