Unformatted text preview: s at equilibrium? 10) For the reaction CO2 (g) + H2 (g) CO (g) + H2O (g) at 686°C, the following are found to be equilibrium concentrations: [CO2] = 0.081 M, [H2] = 0.034 M, [CO] = 0.072 M and [H2O] = 0.020 M. What K for this reaction? 11) K for the reaction of 2 HCl (g) H2 (g) + Cl2 (g) is 4.17 x 10 ­34 at 25°C. What is the equilibrium constant for the reaction of H2 (g) + Cl2 (g) 2 HCl (g) at the same temperature? 12) In question 11, if the equilibrium concentrations of H2 and Cl2 are found to be 1.00 x 10 ­17 M, what is the equilibrium concentration of HCl? 13) For the reaction H2 (g) + Br2 (g) 2 HBr (g), K = 2.18 x 106 at 730°C. What is Q if the initial concentration of both H2 and Br2 are 0.0051 M and the initial concentration of HBr is 0.351 M? 14) For problem 13, if HBr is added to the reaction, will Q increase, decrease or remain the same? 15) For problem 13, what will happen to Q in the volume of the reaction vessel is halved? The reagents are gases so this can be done. Will Q increase, decrease or remain the same? 16) For problem 13, as the reaction is allowed to sit, will Q increase or decrease based on the initial conditions provided? The next four questions refer to the following reaction that you may consider to be at equilibrium: N2 (g) + 3 H2 (g) 2 NH3 (g) 17) Which way will the reaction shift if NH3 is added to the reaction? 18) Which way will the reaction shift if N2 is removed from the reaction? 19) Which way will the reaction shift if H2 is added to the reaction? 20) Which way will the reaction shift if the volume of the container is doubled?...
