When `H_(2)` and `I_(2)` are mixed and equilibrium is attained,then

A

amount of HI formed is equal to the amount of `H_(2)` dissociated

B

HI dissociation stops

C

the reaction stops completely

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
`(a) H_(2)+I_(2) rarr 2HI_(2)`
`:. ` 1 mole of `H_(2)` gives 2 moles of HI.
`(b)` At equilibrium the backward and forward reactions do not stop.
(c ) The reaction does not stop but `R_(f) =R_(b)`.
