Ammonium hydrogen sulfide dissociates into ammonia gas and hydrogen sulfide gas.
If we start with a sample of pure NH4HS(s) at 25 degrees Celsius, the total pressure of the gases is 0.658 atm when equilibrium is established. Write an equation for the dissociation reaction and determine the value of Kp.
(Use the lowest possible coefficients.)
It shows how to calculate the equilibrium constant Kp for the NH4HS dissociation given the total equilibrium pressure. The solution was rated '5/5' by the student who originally posted the question.
