Question

`3.2` moles of hydrogen iodide were heated in a sealed bulb at `444^(@)C` till the equilibrium state was reached. Its degree of dissociation at this temperaturee was found to be `22%` The number of moles of hydrogen iodide present at equlibrium are
A. `2.496`
B. `1.84`
C. 2
D. 4

Answer 1

Correct Answer - A
`22/100xx3.2=0.704`
`therefore"at equil. moles of"HI=3.2-0.704=2.496`
