Question

For a system of gases A, B, C, and D at equilibrium $A+2B\rightleftharpoons C+3D$, the partial pressures are found to be $A=2.0,B=2.0,C=3.$0, and $D=5.0atm$. The value of equilibrium constant is :

• A. $46.87$
• B. $93.75$
• C. $187.4$
• D. None of these

Answer 1

Answer: (A)

$46.87$

$A+2B\rightleftharpoons C+3D$,

$(K=\frac{\left[C\right][D{]}^3}{\left[A\right][B{]}^2}=\frac{3\times (5{)}^3}{\left(2\right)\times (2{)}^2})=46.875$

Hence, option A is correct
