Question

The equilibrium $A\left(g\right)+4B\left(g\right)\rightleftharpoons {AB}_4\left(g\right)$ is attained by mixing equal moles of A and B in a vessel then at equilibrium :

• A. $\left[A\right]=\left[B\right]$
• B. $\left[A\right]>\left[B\right]$
• C. $\left[A\right]<\left[B\right]$
• D. $\left[{AB}_4\right]>\left[A\right]$

Answer 1

The correct option is B $\left[A\right]>\left[B\right]$

$A_{\left(g\right)}+4B_{\left(g\right)}\rightleftharpoons {AB}_{4\left(g\right)}$

$1$ $1$ $-$

$1-x$ $1-4x$

$\left[A\right]>\left[B\right]$
