Another mixture of PCl3(g), Cl2(g), and PCl5(g) is at equilibrium at a different temperature in a different vessel. The system at equilibrium is represented by the following box on the left. Then the volume of the vessel is decreased. The box in the middle represents the system before equilibrium is reestablished at the same temperature. In the box attached, draw an appropriate number of each type of molecule to represent a possible new equilibrium.

. Consider the equilibrium 4 NH3(g) + 3 O2(g) = 2 N2(g) + 6 H₂O(g). Predict the effect on the equilibrium concentration by the addition of N₂. A The equilibrium will shift to produce more nitrogen. B The equilibrium will shift to produce more reactants. C The equilibrium will shift to produce more products. D The reaction is already at equilibrium. E None of the above Given: 2P(g) + 3Cl2(g) → 2PC13(g) K Calculate the equilibrium constant for the following reaction. P(g) + 3/2Cl2(g) → PCI(g) AK BK¹ C 2K D 0.5K EK¹/2

A mixture of 0.10 mole NO, 0.050 mole H₂, and 0.10 mole H₂O is placed in a 2.0 L vessel. The following equilibrium is established: + 2 H₂ (g) = N2(g) + 2 H₂O (g) 2 NO At equilibrium [NO] = 0.030 M. The initial concentration of N₂ was not mentioned so you must assume [N₂] = 0. Calculate the equilibrium concentrations (in M) of: More Information X H₂ (g) XN₂ (g) X H₂O (g) Question Answer Your answer -.020 is Your answer .035 is in Your answer .170 is i Tol: 0.0001 Tol: 0.001 Tol: 0.001

Please answer with the correct number of significant digits. At a certain temperature, the equilibrium constant K for the following reaction is 9.7 x 10¹¹: NO₂(g) + CO(g) NO(g) + CO₂(g) Use this information to complete the following table. Suppose a 42. L reaction vessel is filled with 1.2 mol of NO₂ and 1.2 mol of CO. What can you say about the composition of the mixture in the vessel at equilibrium? What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits. NO(g) + CO₂(9) 1 NO₂(9)+CO (9) What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits. 2 NO₂(9)+2CO(g) 1 2 NO(g) +2C0₂(9) There will be very little NO₂ and CO. There will be very little NO and CO₂. Neither of the above is true. K-O K-0 X
