Answer:
The equilibrium concentration of HCl is 0.01707 M.
Explanation:
Equilibrium constant of the reaction =
Moles of ammonium chloride = 0.573 mol
Concentration of ammonium chloride =
Initial: 0.573 0 0
At eq'm: (0.573-x) x x
We are given:
Calculating for 'x'. we get:
The expression of for above reaction follows:
Putting values in above equation, we get:
On solving this quadratic equation we get:
x = 0.01707 M
The equilibrium concentration of HCl is 0.01707 M.
