> As shown in Table 15.2 in the textbook, K₂, for the equilibrium is 4.51 x 10-5 at 450 °C. Part A For each of the mixtures listed here, indicate whether the mixture is at equilibrium at 450 °C or if it must shift toward the reactants or products to achieve equilibrium. Drag the appropriate items to their respective bins. 13 atm NH3. 27 atm N₂. 82 atm H₂ Mixture is at equilibrium 57 atm NH3. 143 atm N₂, no H₂ Mixture must shift toward products to achieve equilibrium 98 atm NH3, 45 atm N₂, 55 atm H₂ N₂(g) + 3H₂(g) 2NH3(g) Reset Help Mixture must shift toward reactants to achieve equilibrium

8) Consider the system below. When equilibrium is restored, how will the number of each type of molecule and the concentration of each substance compare to those before the stress was introduced? Complete the following table using the words "decrease," "same," or "increase." 2 NH,(g) = N,(g) + 3 H,(g) AH = 92.4 kJ/mol Decrease Volume Decrease Temperature N, Equilibrium Concentration Н, NH, N, Equilibrium Number Н, NH,

A chemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature: N₂(g) + 3 H₂(g) ⇒ 2 NH3 (g) K₂=8.x 10-7 He fills a reaction vessel at this temperature with 5.0 atm of nitrogen gas and 6.8 atm of hydrogen gas. Use this data to answer the questions in the table below. Can you predict the equilibrium pressure of NH3, using only the tools available to you within ALEKS? If you said yes, then enter the equilibrium pressure of NH3 at right. Round your answer to 1 significant digit. Oyes O no atm 10 X

Hydrogen and chlorine react to form hydrogen chloride, like this: H,(g) + Cl,(g) → 2 HCl(g) Also, a chemist finds that at a certain temperature the equilibrium mixture of hydrogen, chlorine, and hydrogen chloride has the following composition: compound pressure at equilibrium H2 20.2 atm Cl 2 50.0 atm HC1 7.95 atm Calculate the value of the equilibrium constant K, for this reaction. Round your answer to 2 significant digits. р K 4 x10
