A \(H_2 O( g )+ CO(g) \rightleftharpoons H_2(g)+ CO_2(g)\)
B \(N _2(g)+3 H _2(g) \rightleftharpoons 2 NH _3(g)\)
C \(H _2(g)+ I _2(g) \rightleftharpoons 2 HI ( g )\)
D \(N_2(g)+ O _2(g) \rightleftharpoons 2 NO ( g )\)

Verified Solution

Answer & Solution

Correct Answer

(B) \(N _2(g)+3 H _2(g) \rightleftharpoons 2 NH _3(g)\)

Step-by-step Solution

Detailed explanation

(B) \(K_p\) અને \(K_c\) વચ્ચેનો સંબંધ \(K_p=K_c(R T)^{\Delta n_g}\) દ્વારા અપાય છે, જ્યાં \(\Delta n_g\) એ વાયુરૂપ નીપજોના મોલની સંખ્યા અને વાયુરૂપ પ્રક્રિયકોના મોલની સંખ્યા વચ્ચેનો તફાવત છે.
\(K_p \neq K_c\) માટે, \(\Delta n_g\) શૂન્યેતર હોવો જોઈએ.
\(H _2 O ( g )+ CO ( g ) \rightleftharpoons H _2(g)+ CO _2(g)\) માટે, \(\Delta n_g=2-2=0 \Rightarrow K_p=K_c\)
\(N _2(g)+3 H _2(g) \rightleftharpoons 2 NH _3(g)\) માટે, \(\Delta n_g=2-4=-2 \Rightarrow K_p \neq K_c\)
\(H _2(g)+ I _2(g) \rightleftharpoons 2 HI ( g )\) માટે, \(\Delta n_g=2-2=0 \Rightarrow K_p=K_c\)
\(N _2(g)+ O _2(g) \rightleftharpoons 2 NO ( g )\) માટે, \(\Delta n_g=2-2=0 \Rightarrow K_p=K_c\)

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
