10 moles of `SO_(2)` and 4 moles of `O_(2)` are mixed in a closed vessel of volume 2 litres. The mixture is heated in the presence of Pt catalyst. Following reaction takes place:
`2SO_(2)(g)+O_(2)(g)to2SO_(3)(g)`
Assuming the reaction proceeds to completion.
Select the correct statement.

A

`SO_(2)` is the limiting reagent

B

`O_(2)` is the limiting reagent

C

Both `SO_(2) and O_(2)` are limiting

D

Cannot be predicted

Text Solution

Verified by Experts

The correct Answer is:
B
`underset("10 moles")(2SO_(2(g)))+underset("reagent")underset("limiting")underset("4 moles")(O_(2(g)))rarr2SO_(3(g))`
`SO_(2)` moles remaining = `10-8=2`
