Equilibrium Question 670
Question: Which of the following reactions proceed at low pressure [MP PET 1985; CPMT 1984; MP PMT 1995; RPMT 1997]
Options:
A) $ N_2+3H_2 $ ⇌ $ 2NH_3 $
B) $ H_2+I_2 $ ⇌ $ 2HI $
C) $ PCl_5 $ ⇌ $ PCl_3+Cl_2 $
D) $ N_2+O_2 $ ⇌ $ 2NO $
Show Answer
Answer:
Correct Answer: C
Solution:
At low pressure, reaction proceeds where volume is increasing. This is the favourable condition for the reaction. $ PCl_5 $ ⇌ $ PCl_3+Cl_2 $ .
