(1) N2(g)+3H2(g)⇌2NH3(g),K1\mathrm{N}_2(\mathrm{ g})+3 \mathrm{H}_2(\mathrm{ g}) \rightleftharpoons 2 \mathrm{NH}_3(\mathrm{ g}), \mathrm{K}_1 (2) N2(g)+O2(g)⇌2NO(g),K2\mathrm{N}_2(\mathrm{ g})+\mathrm{O}_2(\mathrm{ g}) \rightleftharpoons 2 \mathrm{NO}(\mathrm{g}), \mathrm{K}_2 (3) H2(g)+12O2(g)⇌H2O(g),K3\mathrm{H}_2(\mathrm{ g})+\frac{1}{2} \mathrm{O}_2(\mathrm{ g}) \rightleftharpoons \mathrm{H}_2 \mathrm{O}(\mathrm{g}), \mathrm{K}_3 The equation for the equilibrium constant of the reaction 2 NH3(g)+52O2\mathrm{NH}_{3}( \mathrm{ g})+\frac{5}{2} \mathrm{O}_{2}(g\mathrm{ g}) \rightleftharpoons2NO(g)+3H2O(g), 2 \mathrm{NO}(\mathrm{g})+3 \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \text{, }\left(K_4\right)ininterms of \mathrm{K}_1, \mathrm{ K}_2andand\mathrm{K}_3 is :

Options

  1. AK1⋅K2 K3\frac{\mathrm{K}_1 \cdot \mathrm{K}_2}{\mathrm{~K}_3}
  2. BK1⋅K32 K2\frac{\mathrm{K}_1 \cdot \mathrm{K}_3^2}{\mathrm{~K}_2}
  3. CK1 K2 K3\mathrm{K}_1 \mathrm{~K}_2 \mathrm{~K}_3
  4. DK2⋅K33 K1\frac{\mathrm{K}_2 \cdot \mathrm{K}_3^3}{\mathrm{~K}_1}

Correct answer

D. K2⋅K33 K1\frac{\mathrm{K}_2 \cdot \mathrm{K}_3^3}{\mathrm{~K}_1}

Step-by-step solution

To calculate the value of K4\mathrm{K}_4 in the given equation we should apply : eqn. (2) ++ eqn. (3)×3−(3) \times 3- eqn. (1) hence K4=K2 K33 K1\mathrm{K}_4=\frac{\mathrm{K}_2 \mathrm{~K}_3^3}{\mathrm{~K}_1}
