3.2 moles of hydrogemn iodide was heted ...

`3.2` moles of hydrogemn iodide was heted in a sealed bulb at `444^(@)C` till the equilibrium state was reached. Its degree of dissociation sat this temperature was found to be `22%`. The number of moles of hydrogen iodide present at equilibrium is

A

2.496

B

1.87

C

2

D

4

Text Solution

Verified by Experts

The correct Answer is:
A
`22/(100) xx 3.2 =0.704`
`:.` at equil. moles of HI =3.2–0.704 = 2.496.
