A 500 mL glass flask is filled at 298 K and 1 atm . pressure with three diatomic gases

X, Y

and

Z

. The initial volume ratio of the gases before mixing was

5: 3: 1

. The density of the heaviest gas in the mixture is not more than 25 times that of the lightest gas. When the mixture was heated, vigorous reactions take place between X and Y and

X

and

Z

in which all the three gases were completely used up. The gases

X, Y, Z

respectively are

Options

A $\mathrm{H}_2, \mathrm{O}_2, \mathrm{~N}_2$
B $\mathrm{H}_2, \mathrm{O}_2, \mathrm{Cl}_2$
C $\mathrm{H}_2, \mathrm{~F}_2, \mathrm{O}_2$
D $\mathrm{O}_2, \mathrm{H}_2, \mathrm{~F}_2$

Correct answer

C. $\mathrm{H}_2, \mathrm{~F}_2, \mathrm{O}_2$
