Question

Which of the following reactions proceed at low pressure.

• A. ⇌ $2 \mathrm { NH } _ { 3 }$
• B. ⇌ $2 H I$
• C. ⇌
• D. $N _ { 2 } + O _ { 2 }$ ⇌ 2 NO

Answer 1

Answer: (C)

⇌

Answer 2

At low pressure, reaction proceeds where volume is increasing. This is the favourable condition for the reaction. ⇌ $\mathrm { PCl } _ { 3 } + \mathrm { Cl } _ { 2 }$ .
