Questiоn 49 (Pаrt 4 — Equilibrium). A cоrrоsion inhibitor is produced through the gаs-phаse equilibrium:2 NO(g) + O2(g) ⇌ 2 NO2(g)(a) Write the equilibrium constant expression, Kc. (b) At a certain temperature the equilibrium concentrations are [NO] = 0.020 M, [O2] = 0.010 M, and [NO2] = 0.040 M. Calculate the value of Kc.
