QAIPM-2011-Ch-1857: NEET 2011 Chemistry - Class 11 AIPM-2011-Ch-1857 Solution: For the reaction \(N_2(g) + O_2(g) 2NO(g)\) the equilibrium…

For the reaction N2(g)+O2(g)⇌2NO(g)N_2(g) + O_2(g) \rightleftharpoons 2NO(g) the equilibrium constant is K1K_1. The equilibrium constant is K2K_2 for the reaction 2NO(g)+O2(g)⇌2NO2(g)2NO(g) + O_2(g) \rightleftharpoons 2NO_2(g) What is K for the reaction NO2(g)⇌12N2(g)+O2(g)NO_2(g) \rightleftharpoons \frac{1}{2}N_2(g) + O_2(g) 2K1/K22K_1/K_2 1/(4K1K2)1/(4K_1K_2) [1/K1K2]1/2[1/K_1K_2]^{1/2} 1/K1K21/K_1K_2
