Dinitrogen tetroxide forms an equilibrium with nitrogen dioxide. Both are gases. In an experiment, 368.0 grams of dinitrogen tetroxide are added to a 2.00 L container at 25.00 °C. The container was left overnight allowing the reaction to reach equilibrium. It was then determined that the equilibrium concentration of nitrogen dioxide is 0.200 M. Find Kc and Kp for the reaction at 25.00 °C. Show ALL work

8. Consider the equilibrium reaction: N2(g) + O2(g) = 2 NO(g) Kp 4.10 x 10³ at 2000°C a) If 1.00 atm of nitrogen gas and 1.00 atm of oxygen gas is mixed with 0.10 atm of nitrogen monoxide in a 500.0 mL container at 2000°C, in which direction will the reaction proceed to reach equilibrium? Show all work to justify your answer. b) What is the concentration of each gas when equilibrium is reached at 2000°C? Show all your work. Equilibrium Partial Pressures: PN₂ = Po₂ = 1.02 atm and PNO = 0.07 atm Use PV = nRT Answer: Equilibrium Concentrations: [N₂] = [0₂] = 5.47 x 10-3 mol/L and [NO] = 4 x 10+ M

Consider the following reaction: CO2(g) + C(graphite) = 2 CO(g) A reaction mixture initially contains 0.56 atm CO2 and 0.32 atm CO. If the equilibrium pressure of CO gas is 0.83 atm, find the equilibrium constant (Kp) for the reaction.
