Solution


Q.

Higher yield of NO in

N2(g)+O2(g)⇌2NO(g) can be obtained at  [ΔH of the reaction =+180.7 kJ mol-1]


(A) higher temperature
(B) lower temperature
(C) higher concentration of N2
(D) higher concentration of O2

Choose the correct answer from the options given below:                  [2025]
1 B, C, D only  
2 A, C, D only  
3 A, D only  
4 B, C only  

Ans.

(2)

N2(g)+O2(g)⇌2NO(g);ΔH=+180.7 kJ mol-1

As the given reaction is endothermic, hence, it will go to the product side on increasing temperature. Also, on adding reactants, the reaction goes towards the product side.

Hence, conditions given in A, C, and D increase the production of NO(g).
