Answer: The equilibrium constant is 
Explanation:
Initial concentration of
= 0.095 M
The given balanced equilibrium reaction is,

Initial conc. 0.095 M 0 M
At eqm. conc. (0.095-x) M (2x) M
Given : 2x = 0.0055
x = 0.00275
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get :


Thus the equilibrium constant is 
Answer:
(A) 800 K (B) 2.4 KW
Explanation:
We have given the COP =1.6
The sink temperature 
We have to find the source temperature, that is 
(A) We know that COP of the heat pump is given by 
So 



(B) We have given the work done =1.5 KW
The rate of heat transfer is given by 
(99% of the total mass). 49% of carbon, 44% of oxygen, 6% of hydrogen, 0.1-0.3% of nitrogen.
