25.4 g of iodine and 14.2g of chlorine are made to react completely to yield a mixture of ICl and ICl3. Calcualte the ratio of moles of ICl and ICl3.

Q:  25.4 g of iodine and 14.2g of chlorine are made to react completely to yield a mixture of ICl and ICl3. Calcualte the ratio of moles of ICl and ICl3.

(A) 1:1

(B) 1:2

(C) 1:3

(D) 2:3

Sol: I2 + 2Cl2 → ICl + ICl3

25.4 gm of Iodine contains 0.1 moles of it

14.2 gm of chlorine contains 0.2 moles of it

∴ Moles of ICl & ICl3 produced will be 0.1 and 0.1. Hence Molar ratio 1: 1

Ans:  (A)
