A) \[8\times {{10}^{-3}}\]
B) \[16\times {{10}^{-3}}\]
C) \[6.25\times {{10}^{4}}\]
D) \[6.25\times {{10}^{6}}\]
Correct Answer: C
Solution :
\[NO(g)+\frac{1}{2}{{O}_{2}}(g)N{{O}_{2}}(g);\]\[{{K}_{1}}=4\times {{10}^{-3}}\] \[4\times {{10}^{-3}}=\frac{[N{{O}_{2}}]}{[NO]{{[{{O}_{2}}]}^{1/2}}}\] On squaring, we get \[16\times {{10}^{-6}}=\frac{{{[N{{O}_{2}}]}^{2}}}{{{[NO]}^{2}}[{{O}_{2}}]}\] ?.(i) \[2N{{O}_{2}}(g)2NO(g)+{{O}_{2}}(g);\] \[{{K}_{2}}=?\] \[{{K}_{2}}=\frac{{{[NO]}^{2}}[{{O}_{2}}]}{{{[N{{O}_{2}}]}^{2}}}\] ?(ii) From Eqs. (i) and (ii), \[{{K}_{2}}=\frac{1}{{{K}_{1}}}=\frac{1}{16\times {{10}^{-6}}}=6.25\times {{10}^{4}}\]You need to login to perform this action.
