the equilibrium constant that refers to the association or ionization off said, is called us ionization constants that is represented by K A high end, the value off a stronger will be the asset. Hear equilibrium, reaction and equilibrium constant are represented. Us follow. The key is much larger for H c o tower, which then etch Cielo first, Equally grim will donate. It has provided that we have dissociation constant for H c o tower, which let x be the change in concentration when reaction reached equilibrium. Thus the concentration at equilibrium can be expressed as follow here. Actually present the more LaSalle ability. Now calculate the more LaSalle ability by applying the assumption that ex CEO to which is equal to 0.25 minus X that comes equal Villain 2.25 Putting in the values we have. The concentric we have, the more LaSalle ability that this X that drowns out Toby 6.71 into attended super minus three. Because this value is 2.68% off 0.1234 Our assumption is correct. That assumption is only valid for less than five points percent concentration. We can also calculate the concentration off X tree or positive, which is 6.7 in tow. Rendition where my necessary by that off ex CEO to etch is 0.25 No, which negative can be calculated using the fine product expression that is kw by EJ 30 positive concentration. It comes out to be 1.5 to 10 days about minus thing Finally used the other equilibrium to find the concentration. Assume that s e l O is 0.10 minus X that is almost equivalent toe 0.10 Doing the calculation as stated above. It turns out to be 4.3 Entertainment super minus seven. Similarly, for ex Cielo, it turns out Toby 4.3 into 10 days, about minus seven.
