The following equilibria are given: [AIPMT 2003] |
\[\begin{matrix} {{N}_{2}}+3{{H}_{2}}2N{{H}_{3}} & {{K}_{1}} \\ \end{matrix}\] |
\[\begin{matrix} {{N}_{2}}+{{O}_{2}}2NO & {{K}_{2}} \\ \end{matrix}\] |
\[\begin{matrix} {{H}_{2}}+\frac{1}{2}{{O}_{2}}{{H}_{2}}O & {{K}_{3}} \\ \end{matrix}\] |
The equilibrium constant of the reaction \[2N{{H}_{3}}+\frac{5}{2}{{O}_{2}}\rightleftharpoons 2NO+3{{H}_{2}}O\] in terms of \[{{K}_{1}},\text{ }{{K}_{2}}\] and \[{{K}_{3}}\] is: |
A) \[\frac{{{K}_{1}}K_{3}^{2}}{{{K}_{2}}}\]
B) \[\frac{{{K}_{2}}\,K_{3}^{3}}{{{K}_{1}}}\]
C) \[{{K}_{1}}\,{{K}_{2}}\,{{K}_{3}}\]
D) \[\frac{{{K}_{1}}\,{{K}_{2}}}{{{K}_{3}}}\]
