A) \[6.37\times {{10}^{-3}}\]
B) \[4.29\times {{10}^{-3}}\]
C) \[5.62\times {{10}^{-3}}\]
D) \[4.37\times {{10}^{-3}}\]
E) None of these
Correct Answer: A
Solution :
\[\Delta {{n}_{g}}={{n}_{p}}-{{n}_{r}}=2-1=1,\] \[{{K}_{c}}=\frac{{{K}_{p}}}{{{(RT)}^{\Delta {{n}_{g}}}}}\] \[=\frac{(0.157\,atm)}{{{(0.0821\,\,L\,\,atm\,{{K}^{-1}}\,mo{{l}^{-1}}\,\times \,300\,K)}^{1}}}\] \[=6.37\times {{10}^{-3}}\,mol\,{{L}^{-1}}\]You need to login to perform this action.
