A) 1.2
B) 2.4
C) 3.6
D) None of these
Correct Answer: B
Solution :
\[\begin{align} & A\,\,\,\,+\,\,\,\,B\,\,\rightleftharpoons \,\,\,2C \\ & 2\,\,\,\,\,\,\,\,\,\,\,\,3\,\,\,\,\,\,\,\,\,\,\,\,\,0\, \\ & 2\,-\,x\,\,\,\,3-x\,\,\,\,2x \\ \end{align}\] \[{{K}_{c}}=\,\,\frac{{{\left[ C \right]}^{2}}}{\left[ A \right]\left[ B \right]}\] \[4=\frac{4{{x}^{2}}}{(2-x)(3-x)}\] \[4(6-3x-2x+{{x}^{2}})=4{{x}^{2}}\] \[4\left( {{x}^{2}}-5x+6 \right)=4{{x}^{2}}\] \[5x=6\] \[x=1.2\]You need to login to perform this action.
