Question
pleae help with these quesitons. ill offer a LOT of points plz
What is the value of Kc if PNO2=3PN2O4? N2O4 (g) 2NO2(g) (A) 3(PNO2)2/RTPNO2 (B) (PNO2)2/PNO2 (C) (PNO2)2/(3RT PNO2) (D) (PNO2)2/(3PNO2) (E) (RTPNO2)/3(PNO2)2 The Kc for the reaction COCl2(g) CO(g) +Cl2(g) at 125 degree C is 1.61x104. Given the concentrations [COCl2]=0.174 M, [CO]= 2.10x10-5 M and [Cl2]=2.10x10-5 M one can conclude that: the system is at equilbrium and the reaction will Proceed to the left the system is at equilibrium and no net change will occur the system is not at equilibrium and the reaction will proceed to the right no conclusions can be made from the given data The gaseous disproportionation of CIF to give Cl2 and F2. 2 CIF Cl2 + F2, has a Kp at 50degree C of2S.0. If a sample of CIf pressure of 2.2 atm is allowed to react, what will be the equilibrium partial pressure of Cl2? (A) 2.00 atm (B) 1.83 atm (C) 1.08 atm (D) 2.12atm At a certain temperature. Kp = 36 for the reaction NH4Cl(s) NH3(g) +HCl(g). What is the TOTAL pressure in atm, for the at equilibrium when a given amount of NH4Cl(s) decomposes (A) 36 (B) 12 (c) 6 (D) 1.3x103 (E) More information is required. Barium hydroxide is a strong base. Compute [Ba2+] and [OH] for a solution that is prepared by dissolving 6.0x10 hydroxide in 500.0mL of water. (A) 1.2x10-2, 2.4x10-2 (B) 1.2x10-1, 2.4x10-1 (C) 1.2x102, 1.2x10-2 (D) 1.2x10-1, 1.2x10-1 (E) 2.5x10-1, 1.2x10-1
