${NH}_{4}HS ( s ) ⇌ {NH}_{3} ( g ) + {H}_{2}S ( g )$
In the above reaction, if the pressure at equilibrium and at $300K$ is $100atm$ then what will be the equilibrium constant ${K}_{p}$?

Step-by-step solution

Given,

Total pressure at equilibrium $= P + P = 100atm$

$⇒ 2P = 100atm$

$⇒ P = 50atm$

${K}_{P} = \left[{P}_{NH₃}\right] \times \left[{P}_{{H}_{2}S}\right]<br /><br />${K}_{P} = 50 $\times50 = 2500{atm}^{2}$
