Question

An equilibrium mixture of H2, I2, and HI at 458 ∘C contains 0.112 molH2, 0.112 molI2, and 0.775 molHI in a 5.00-L vessel.

Part A: What are the equilibrium partial pressure of HI when equilibrium is reestablished following the addition of 0.200 mol of HI? Express your answer to four significant figures and include the appropriate units.

Part B:What are the equilibrium partial pressure of I2 when equilibrium is reestablished following the addition of 0.200 mol of HI? Express your answer to three significant figures and include the appropriate units.

Part C:What are the equilibrium partial pressure of H2 when equilibrium is reestablished following the addition of 0.200 mol of HI? Express your answer to three significant figures and include the appropriate units.

Answer 1

Solo Given Temperature T+ 158°C = 15872:13 - 220K volume, VE 5.00€ Now we have to write the seation under In the equilibrium condition is - Hey + 129 + 2 H2493 Now we have to find the equilibrium Constant for the above reaction. Given to on G H = 40.775 moles of H₂ = 0.112 moles of a = 0.112 (Hj] ok . 10.775) (0.112) (0.112) - 0.600675 0.012544 Kep - 17:581] H₂ + 12 → 2 H 1 Tab change at 7. btx (+0.2 We need to find the concentration of of the - reaction,
