#### In the reaction, Option 1)   at STP  is produced for every mole   consumed Option 2)   is consumed for ever      produced Option 3) is produced regardless of temperature and pressure for every mole Al that reacts Option 4) at STP is produced for every mole Al that reacts .

As we learnt in

Number of Moles of a gas at STP -

no of moles of a gas at STP= given volume of gas / 22.4 liter

-

In given problem 2 mole Al produce 3 mole H2(g)

Hence 1 mole Al give  mole H2(g)

Volume of 1 mole H2 at STP is 22.4 L

Volume of  mole H2 at STP

Ans. option 3

Option 1)

at STP  is produced for every mole   consumed

This is an incorrect option.

Option 2)

is consumed for ever      produced

This is an incorrect option.

Option 3)

is produced regardless of temperature and pressure for every mole Al that reacts

This is the correct option.

Option 4)

at STP is produced for every mole Al that reacts .

This is an incorrect option.
