Answer : The volume of
produced are 90.7 liters.
Explanation :
The balanced chemical reaction will be:
First we have to calculate the moles of PbS.
Molar mass of PbS = 239.26 g/mole
Now we have to calculate the moles of
by using ideal gas equation.
Using ideal gas equation :
where,
P = Pressure of
gas = 2.00 atm
V = Volume of
gas = 123 L
n = number of moles
= ?
R = Gas constant =![0.0821L.atm/mol.K](/tpl/images/0341/6560/a454c.png)
T = Temperature of
gas = ![220^oC=273+220=493K](/tpl/images/0341/6560/32eb2.png)
Putting values in above equation, we get:
The number of moles of
is, 6.07 mole
Now we have to calculate the limiting and excess reagent.
From the balanced reaction we conclude that
As, 3 mole of
react with 2 mole of ![PbS](/tpl/images/0341/6560/db675.png)
So, 6.07 moles of
react with
moles of ![PbS](/tpl/images/0341/6560/db675.png)
From this we conclude that,
is an excess reagent because the given moles are greater than the required moles and
is a limiting reagent and it limits the formation of product.
Now we have to calculate the moles of![SO_2](/tpl/images/0341/6560/0196d.png)
From the reaction, we conclude that
As, 3 mole of
react to give 2 mole of ![SO_2](/tpl/images/0341/6560/0196d.png)
So, 6.07 moles of
react to give
moles of ![SO_2](/tpl/images/0341/6560/0196d.png)
Now we have to calculate the volume of
produced at STP.
As, 1 mole of
contains 22.4 L volume of ![SO_2](/tpl/images/0341/6560/0196d.png)
So, 4.05 mole of
contains
volume of ![SO_2](/tpl/images/0341/6560/0196d.png)
Therefore, the volume of
produced are 90.7 liters.
