What volume of #O_2# (g) at #350^oC# and a pressure of 5.25 atm is needed to completely convert 5.00 g of sulfur to sulfur trioxide?
#SO_3#, is produced in enormous quantities each year for use in the synthesis of sulfuric acid.
#S (s) + O_2 (g) -> SO_2 (g)#
#2SO_2 (g) + O2 (g) -> 2SO_3 (g)#
We can combine the given equations........
And this clearly gives us the mass transfer; 1 equiv of sulfur is oxidized by 3/2 equiv dioxygen gas.....
And so we need
And we use the Ideal Gas Equation.......
