A) \[[{{(0.75)}^{3}}(0.25)]\div [{{(1.00)}^{2}}(1.00)]\]
B) \[[{{(0.75)}^{3}}(0.25)]\div [{{(0.50)}^{2}}(0.75)]\]
C) \[[{{(0.75)}^{3}}(0.25)]\div [{{(0.50)}^{2}}(0.25)]\]
D) \[[{{(0.75)}^{3}}(0.25)]\div [{{(0.75)}^{2}}(0.25)]\]
Correct Answer: B
Solution :
\[2A+B\rightleftharpoons 3C+D\]Initial conc. | 1 | 1 | ||
Reacted | .5 | .5 | ||
Produced | .75 | .75 | ||
At. equilibrium | .5 | .75 | .75 | .25 |
\[{{K}_{c}}=\frac{(0.25)\times {{\left( 0.75 \right)}^{3}}}{{{\left( 0.5 \right)}^{2}}\times \left( 0.5 \right)}\] |
