This is an incomplete question, here is a complete question.
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:
Answer :
(a) 0.0152
(b) 0.0000000778
(c) 0.000001
(d) 1600.1
Explanation :
Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.
For example :
5000 is written as
889.9 is written as
In this examples, 5000 and 889.9 are written in the standard notation and and are written in the scientific notation.
(a)
The standard notation is, 0.0152
(b)
The standard notation is, 0.0000000778
(c)
The standard notation is, 0.000001
(d)
The standard notation is, 1600.1
