For the gas phase decomposition of nitrogen dioxide at 383 °C 2 NO2—2 NO + O2
the average rate of disappearance of NO2 over the time period from t = 0 s to t = 12 s is found to be 1.3610-2 Ms 1.
The average rate of formation of O2 over the same time period is
Ms-1

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
