Chapter 11, Problem 113E

Consider the reaction:

$2{\text{SO}}_2\left(g\right)+{\text{O}}_2\left(g\right)\to 2{\text{SO}}_3\left(s\right)$

If 285.5 mL of ${\text{SO}}_2$ is allowed to react with 158.9 mL of ${\text{O}}_2$

(both measured at STP), what are the limiting reactant and the theoretical yield of ${\text{SO}}_3$

?

If 2.805 g of ${\text{SO}}_3$ is collected (measured at STP), what is the percent yield for the reaction?
