Calculate the value of the equilibrium constant, K c , for the reaction AgCl ( s ) + Cl − ( aq ) − ⇀ ↽ − AgCl − 2 ( aq ) K c = ? The solubility product constant, K sp , for AgCl is 1.77 × 10 − 10 and the overall formation constant, K f ( β 2 ), for AgCl − 2 is 1.8 × 10 5 .

The equilibrium constant is  Kc  

Explanation:

      The equation for the formation of can also be defined as  

Now the formation constant is mathematically represented as

                for the formation of

Substituting parameters

Now the value of  

    The solubility product is mathematically represented as

For

The value is given as

The equation given to us in this question is

The equilibrium constant is mathematically represented as

For the above equation

Now

Substituting values

Therefore

                     Kc  

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
