Consider the balanced equation below. Upper P Upper C l Subscript 3 Baseline + Upper C l Subscript 2 Baseline right arrow Upper P Upper C l Subscript 5. What is the mole ratio of PCl3 to PCl5? 1:1 2:1 3:5 5:3

Answer : The mole ratio of to is 1 : 1.

Explanation :

Balanced chemical reaction : It is a chemical reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

The balanced chemical reaction is:

By the stoichiometry of the reaction we can say that 1 mole of reacts with 1 mole of to give 1 mole of .

From this we conclude that the mole ratio of to is 1 : 1.

Hence, the mole ratio of to is 1 : 1.
