The reduction of iron(III) oxide to iron during steel-making can be summarized by this sequence of reactions:

;    

;    

The net reaction is:

;    

Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K be sure you use their standard symbols.

Answer : The equilibrium expression will be:

Explanation :

The intermediate reaction are:

(1) ;    

(2) ;    

The net reaction is:

;    

Now we are multiplying reaction 1 by 3 and reaction 2 by 2 and then adding both the reaction we get the net reaction.

(1) ;    

(2) ;    

If the equation is multiplied by a factor of '2' or '3', the equilibrium constant will be the power of 2 or 3 of the equilibrium constant of initial reaction.

If the equations are added then the equilibrium constant of the reactions will be multiplied.

Thus the equilibrium expression will be:

here are some of the ways in which chemical and nuclear reactions differ.
