JEE Main & Advanced Chemistry Equilibrium / साम्यावस्था Question Bank Topic Test - Chemical Equilibrium (6-5-21)

\[K\] for the synthesis of \[HI\] is 50. \[K\] for dissociation of \[HI\] is

A) 50

B) 5

C) 0.2

D) 0.02

Correct Answer: D

Solution :

[d] \[{{K}_{{{c}_{1}}}}\] for \[{{H}_{2}}+{{I}_{2}}\]\[\rightleftharpoons \] 2HI is 50

\[{{K}_{{{c}_{2}}}}\] for 2HI \[\rightleftharpoons \]\[{{H}_{2}}+{{I}_{2}}\]

\[{{K}_{{{c}_{2}}}}=\frac{1}{{{K}_{{{c}_{1}}}}}=\frac{1}{50}=0.02\]
