Dinitrogen tetraoxide, a colorless gas, exists in equilibrium with nitrogen dioxide, a reddish brown gas. One way to represent this equilibrium is: NO2(g) 1/2 N20,(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) 2NO2(g) N20(g) K1 = 2) N204(g). =2NO2(g) K2= (1/K) 3) 1/2 N204(g) = NO2(g) K3 = 1/K Drag and drop your selection from the owing list to complete the answer: (1/K)?
