Consider the following reaction: NH4HS(s)⇌NH3(g)+H2S(g)An equilibrium mixture of this reaction at a certain temperature was found to have [NH3]= 0.272 MM and [H2S]= 0.355 MM. You may want to referenceWhat is the value of the equilibrium constant (Kc) at this temperature?

Ibelieve y y even though i've only taken chemistry for one year

Bthats what im doing to and i figured it out it is b

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
