Answer:

4 moles of 

and 1 mole of 

will be present in the reaction vessel

Explanation:

The reaction given in the question is

According to the stoichiometric coefficients of the reaction, 2 moles of 

requires 3 moles of 

so in this reaction, 

is a limiting reagent. So we will consider that 

is in excess.

Now,

Since 3 moles of 

requires 2 moles of

So, for 6 moles of 

the moles of 

required = 

= 4 moles.

Moles of 

remaining after the completion of reaction = 5 - 4 = 1 mole.

Again,

Since 3 moles of 

produces 2 moles of

So, moles of 

produced by 6 moles of 

= 4 moles.

Therefore, after the completion of reaction, 4 moles of 

and 1 mole of 

will be present in the reaction vessel.
