A) \[7.5\times {{10}^{-5}}\]
B) \[2.5\times {{10}^{-5}}\]
C) \[2.5\times {{10}^{-4}}\]
D) \[1.72\times {{10}^{-4}}\]
Correct Answer: D
Solution :
\[2NOCl(g)\rightleftharpoons 2NO(g)+C{{l}_{2}}(g)\] \[{{K}_{c}}=3\times {{10}^{-6}}L\,mo{{l}^{-1}},\] \[T=427+273=700\,K\] \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] \[\Delta n=3-2=1\] \[{{K}_{p}}={{K}_{c}}RT\] \[=3\times {{10}^{-6}}\times 0.0821\times 700\] \[=172.4\times {{10}^{-6}}=1.72\times {{10}^{-4}}\]You need to login to perform this action.
