Solid nh4hs is introduced into an evacuated flask at 24 ∘c. the following reaction takes place: nh4hs(s)⇌nh3(g)+h2s(g) at equilibrium the total pressure (for nh3 and h2s taken together) is 0.614 atm.

0.09425

Explanation:

The reactant is in solid phase and therefore has zero partial pressure.

The products have the same mole ratio (1:1) and will have the same partial pressure = 1/2 × 0.614 atm = 0.307 atm

Kp =  (NH3)(H2S) = 0.09425

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
