ANSWER

I

+2Cl

2

→ICl+ICl

3

Molar mass of I

2

=127

Molar mass of Cl

2

=70.9

Moles of I

2

used =

127

25.4

= 0.2 moles of I

2

Moles of Cl

2

used =

70.9

14.2

= 0.2 moles of Cl

2

Since the stoichiometry indicates that each mole of I

2

reacts with 2 moles of Cl

2

to give 1 mole each of ICl and ICl

.

Chlorine is limiting reagent, in this case.

Hence 0.2-mole chlorine will react with 0.1 moles of iodine to form 0.1 mole each of the product.

Hence, the correct option is A
