Consider the reaction: H2(g) + CO2(g) в‡„ H2O(g) + CO(g) 0. 80 mole of H2 and 0. 80 mole of CO2 are put in a 5-dm container by 1650 C. At balance, 0. 25 mole of CO was found in the equilibrium combination. Calculate the equilibrium frequent K c. (0. 2) 3 o
For the reaction:
2NO2(g) в‡„ N2O4(g), the value of Kc is zero. 5 for 450 C.
A 1-L container includes 2 . zero moles NO2 and installment payments on your 0 gopher N2O4 400 C. Is definitely the mixture by equilibrium? If perhaps not, in which direction must the reaction go to reach balance? 8. Kc and Kc are the balance constants to get reactions We and II respectively. I. II. a) b) c) 9. 3H2(g) + N2(g) в‡„ 2NH3(g) Ві/2 H2(g) + ВЅ N2(g) в‡„ NH3(g) ' '
Write the equilibrium frequent expressions to get Kc and then for Kc. Get a numerical relationship ' between Kc and Kc. A reaction vessel contains an equilibrium combination of 0. eleven M And 2(g), 1 . 91 Meters H2(g) and 0. 25 M NH3(g) o for 500 C. Calculate the equilibrium frequent, Kc intended for reaction My spouse and i. (0. 082) ' Compute also the equilibrium continuous, Kc pertaining to reaction II. (0. 29) 4 um
For the response: 2NO(g) + Cl2(g) в‡„ 2NOCl(g), Kp is six. 5 times 10 in 35 C. At sense of balance, the part pressure PNO = zero. 35 atm and PCl2 = zero. 10 atm. Calculate the equilibrium partial pressure of NOCl. (28. 2 atm)
Pertaining to the reaction: C(s) + 2H2(g) в‡„ CH4(g), Kp can be 0. 262 at a thousand C. For equilibrium, the partial pressure PH2 sama dengan 1 . twenty two atm. Calculate the balance partial pressure of CH4(g). (0. 39 atm) um
1 ) 0 skin mole of PBr5 is added to a 1-dm container in 200 C and is in order to attain equilibrium according to the response: PBr5(g) в‡„ PBr3(g) & Br2(g) The equilibrium mix contains zero. 61 skin mole of PBr5(g) a) b) Calculate the partial pressure of each of the components in the container. (PPBr5 = twenty three. 7 atm; PPBr3 = 15. 15 atm) Determine the Kp for the reaction. (Kp sama dengan 9. 68)
Phosgene gas (COCl2) is a highly toxic substance. 3. 00 x 10пЂ2 mol in the gas was placed in a one. 50-L textbox. It was warmed to 800K. An balance is established: COCl2 (g) в‡„ CO(g) + Cl2(g) The equilibrium pressure of CO was 0. 497 credit. Calculate: a) b) the number of mol of CO in the equilibrium combination. the equilibrium constant Kc and Kp.
