When the following reaction reached equilibrium at 325 K, the equilibrium constant was found to be 172. When a sample was taken of the equilibrium mixture, it was found to contain 0.0714 M NO2. What was the equilibrium concentration of N2O4? 2NO2(g) ⇋  N2O4(g)

Dinitrogen tetraoxide, a colorless gas, exists in equilibrium with nitrogen dioxide, a reddish brown gas. One way to represent this equilibrium is: 2NO2(g)N,04(g) We could also write this reaction three other ways, listed below. The equilibrium constants for all of the reactions are related. Write the equilibrium constant for each new reaction in terms of K, the equilibrium constant for the reaction above. 1/2 K1 1) N,O4(2) (5)-ON = K2 1/2 2) NO2(g) N204(g) K3 3) N204(g) = 2NO2(g) Drag and drop your selection from the following list to complete the answer: (1К)12 K12 1/K

4. The formation of glucose from water and carbon dioxide is an extremely important reaction for life to exist. Plants perform this reaction through the process of photosynthesis, creating the base of the food chain. The UNBALANCED equation is: H₂O (9) CO2 (g) C6H12O6 (s) + O2 (g) At a particular temperature the equilibrium concentrations were found to be: [H₂0] = 7.90x10-2M, [CO₂] = 0.930M, [0₂] =2.40x10-³M. a. Balance the equation. b. Write an expression for Kc- c. Calculate the value of Kc for the reaction at equilibrium.

Which is true of a system at equilibrium when Kc < 1? O Equilibrium favors neither reactants or products Equilibrium favors products O Equilibrium favors reactants Equilibrium is shifting to the left Equilibrium is shifting to the right
