3.2 moles of hydrogen iodide were heated in a sealed bulb at 444
ºC till the equilibrium state was reached. Its degree of dissociation at
this temperature was found to be 22. The numbers of moles of hydrogen
iodide present at equilibrium are

A2.496B1.87C2D4

Show answer and solution▾

$\frac{22}{100}$ × 3.2 = 0.704
[IMAGE] at equil. moles of HI = 3.2 - 0.704 = 2.496
