Higher yield of NO in N2(g) + O2(g) ⇌ 2NO(g) can be obtained at [∆H of the reaction = +180.7 kJ mol^(–1) ] ​

Question

Higher yield of NO in \(N_2(g) + O_2(g) \rightleftharpoons 2NO(g)\)  can be obtained at [\(\Delta H\) of the reaction = \(+ 180.7 \ kJ \ mol^{-1}\) ] 

A. Higher temperature 

B. Lower temperature 

C. Higher concentration of \(N_2\) 

D. Higher concentration of \(O_2\) 

Choose the correct answer from the options given below : 

(1) A, D only 

(2) B, C only 

(3) B, C, D only 

(4) A, C, D only

Answer 1

Correct option is: (4) A, C, D only

\(N_2(g) + O_{2(g)} \rightleftharpoons 2NO_{(g)}; \Delta H = + 180.7 \ kJ \ mol^{-1}\)

(A) as \(T\uparrow \Rightarrow \text{reaction shifts forward}\)

(B) as \(T\downarrow \Rightarrow \text{reaction shifts backward}\)

(C) as \([N_2]\uparrow \Rightarrow \text{reaction shifts forward}\)

(D) as \([O_2] \uparrow \Rightarrow \text{reaction shifts forward}\)
