Consider the following reaction:
Fe3+(aq)+SCN−(aq) <> FeSCN2+(aq)
A solution is made containing an initial [Fe3+] of 1.1 x 10^−3 M and an initial [SCN−] of 7.8 x 10^−4 M . At equilibrium, [FeSCN2+]= 1.6 x 10^−4 M .
Part A) Calculate the value of the equilibrium constant (Kc).
Express your answer using two significant figures.

The value of the equilibrium constant is .

Explanation:

Initially

           0

At equilibrium :

           x

The concentration of at equilibrium is given ,x=

The expression of an equilibrium constant is given as;

Putting value of x:

The value of the

The value of the equilibrium constant is .

h let me think

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
