The generic metal a forms an insoluble salt ab(s) and a complex ac5(aq). the equilibrium concentrations in a solution of ac5 were found to be [a] = 0.100 m, [c] = 0.0160 m, and [ac5] = 0.100 m. determine the formation constant, kf, of ac5.

To solve this problem, we must remember that the Kf is simply the ratio of the concentration of the products over the reactants. The balanced equation is:

A +  5 C -->  AC5

Therefore Kf is:

Kf = [AC5] / [A] [C]^5

Kf = 0.100 / [0.100 * 0.0160^5]

Kf = 953,674,316.4 = 9.5 x 10^8

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
