Consider the reaction: p(s) + 3/2 cl2( g. pcl3( g. write the equilibrium constant for this reaction in terms of the equilibrium constants, ka and kb, for reactions a and b below: a.)p(s) + 5/2 cl2( g. pcl5( g. ka b.)pcl3( g. + cl2( g. pcl5( g. kb

The equilibrium constant for the total reaction is

Explanation:

We are given two intermediate equations:

Equation 1:  

The expression of for the above equation is:

      ......(1)

Equation 2:  

The expression of for the above equation is:

      ......(2)

Now, dividing expression 1 by expression 2, we get:

The above expression is the expression for the total equation, which is:

Hence, the equilibrium constant for the total reaction is

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
