A solid $XY$ kept in an evacuated sealed container undergoes decomposition to form a mixture of gases $XandY$ at temperature $T$ .

The equilibrium pressure is $10bar$ in this vessel. ${K}_{p}$ for this reaction is?

Options

A $25$
B $100$
C $10$
D $5$

Correct answer

A. $25$

Step-by-step solution

\begin{cases}XY & ⇌ & X \\ ( S ) & ( g )\end{cases}

\begin{array}{ll}+ & Y \\ ( g )\end{array}

<br /><br />${P}_{eq} = {P}_{x} + {P}_{x}

= 10

<br /><br />

⇒ {P}_{x} = 5

<br /><br />

{K}_{p} = \left({P}_{x}\right) . ( {P}_{y} )

<br /><br />

= 5 \times 5 = 25$
