A) 12
B) 21
C) 10
D) 11
Correct Answer: B
Solution :
\[N{{H}_{2}}COON{{H}_{4}}(s)\rightleftharpoons \] \[{{N}_{2}}(g)\,+3{{H}_{2}}(g)\,+CO(g)\,+\frac{1}{2}\,{{O}_{2}}(g)\] \[p\,\,\,\,\,\,\,\,\,\,\,\,\,3p\,\,\,\,\,\,\,\,\,\,\,p\,\,\,\,\,\,\,\,\,\,\,\,\,\,\frac{p}{2}\] Total pressure at equilibrium = 2 atm \[p+3p+p+\frac{p}{2}\,=22\] \[\Rightarrow \,\frac{11}{2}\,p=22\,\,\,\Rightarrow \,p=4\,\,atm\] \[Kp=p\,{{(3p)}^{3}}p\sqrt{\frac{p}{2}}\] \[\Rightarrow \,27\times {{2}^{\lambda /2}}\,=27{{(4)}^{11/2}}\,{{2}^{-1/2}}\] \[\Rightarrow \,\,{{2}^{\lambda /2}}\,={{2}^{21/2}}\]\[\lambda =21\]You need to login to perform this action.
