A possible mechanism for the gaseous reaction 2 {\H}_2+2 {\NO} \to 2 {\H}_2 {\O}+ {\N}_2 is Step 1: 2 {\NO} ⇌ {\N}_2 {\O}_2 Step 2: {\N}_2 {\O}_2+ {\H}_2 \to {\N}_2 {\O}+ {\H}_2 {\O} (slow) Step 3: {\N}_2 {\O}+ {\H}_2 \to {\N}_2+ {\H}_2 {\O} The rate law for this reaction is [TG EAPCET 14 May 2023 Shift 2]

Correct Answer is : R=k[NO]2[H2]

{\R}= {\k}[ {\NO}]^2 [ {\H}_2] ^2

{\R}= {\k}[ {\NO}] [ {\H}_2] ^2

{\R}= {\k}[ {\NO}]^{1 \/ 2} [ {\H}_2]

Marks: +1, -0

A possible mechanism for the gaseous reaction 2H2+2‌NO→2H2O+N2 is
Step 1: 2‌NO⇌N2O2
Step 2: N2O2+H2→N2O+H2O (slow)
Step 3: N2O+H2→N2+H2O
The rate law for this reaction is

[TG EAPCET 14 May 2023 Shift 2]

R=k[NO]2[H2]2
R=k[NO][H2]2
R=k[NO]1∕2[H2]
R=k[NO]2[H2]
