A) \[5\]
B) \[3\]
C) \[6\]
D) \[4.5\]
Correct Answer: D
Solution :
\[\underset{\begin{smallmatrix} 3mol \\ (3-x)mol \end{smallmatrix}}{\mathop{PC{{l}_{5}}}}\,\rightleftharpoons \underset{(3+x)mol}{\mathop{\underset{3mol}{\mathop{PC{{l}_{3}}}}\,}}\,+\underset{(2+x)mol\,at\,equlibrium}{\mathop{\underset{2\text{mol}\,\text{intially}}{\mathop{C{{l}_{2}}}}\,}}\,\] \[\because \] \[3-x=1.5\] \[x=1.5\] Number of moles of \[PC{{l}_{3}}=3+x\] \[=3+1.5=4.5\]You need to login to perform this action.
