# Given the equilibrium reaction $\mathrm{A}\left(\mathrm{g}\right)+2\mathrm{B}\left(\mathrm{g}\right)⇌2\mathrm{C}\left(\mathrm{g}\right)$. This reaction is studied by starting with equal amounts of A and Bin a constant-volume vessel. Which of the following expressions will hold good?

1. A

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

2. B

$\left[\mathrm{C}\right]=\left[\mathrm{B}\right]$

3. C

$\left[\mathrm{B}\right]<\left[\mathrm{A}\right]$

4. D

$\left[\mathrm{A}\right]<\left[\mathrm{B}\right]$

### Solution:

given chemical equation,

$\begin{array}{l}\mathrm{A}\left(\mathrm{g}\right)+2\mathrm{B}\left(\mathrm{g}\right) ⇌2\mathrm{C}\left(\mathrm{g}\right)\\ {a}_{0}-x {a}_{0}-2x\end{array}$

Obviously, $\left[\mathrm{B}\right]<\left[\mathrm{A}\right]$
