Third choice because the others make no sense
Answer:
first of all we have to put sugar in bread and we have to add some ginger paste over it
Explanation:
Chemical reaction equation for the give decomposition of
is as follows:.

And, initially only
is present.
The given data is as follows.
= 2.3 atm at equilibrium
= 0.69 atm
Therefore,

= 0.23 aatm
So,
= 2.3 - 2(0.23)
= 1.84 atm
Now, expression for
will be as follows.


= 
= 0.0224
or, 
Thus, we can conclude that the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture is
.
