A) 100
B) 0.010
C) 0.10
D) 1000
Correct Answer: C
Solution :
For the reaction, \[{{N}_{2}}+2{{O}_{2}}2N{{O}_{2}}\] \[{{K}_{c}}=\frac{{{[N{{O}_{2}}]}^{2}}}{[{{N}_{2}}]\,\,{{[{{O}_{2}}]}^{2}}}=100\] ?. (i) For the reaction, \[N{{O}_{2}}\frac{1}{2}{{N}_{2}}+{{O}_{2}}\] \[{{K}_{c}}=\frac{{{[{{N}_{2}}]}^{1/2}}[{{O}_{2}}]}{[N{{O}_{2}}]}\] or \[{{({{K}_{c}})}^{2}}=\frac{[{{N}_{2}}]\,[{{O}_{2}}]}{{{[N{{O}_{2}}]}^{2}}}\] \[=\frac{1}{100}\] (from equation (i)] \[\therefore \] \[K_{c}^{}=\sqrt{\frac{1}{100}}=\frac{1}{10}=0.10\]You need to login to perform this action.
