Chapter 11, Problem 114E

Consider the reaction:

${\text{P}}_4\left(s\right)+6{\text{H}}_2\left(g\right)\to 4{\text{PH}}_3\left(g\right)$

If 88.6 L of ${\text{H}}_2\left(g\right)$, measured at STP, is allowed to react with 158.3 g of ${\text{P}}_4$, what is the limiting reactant?

If 48.3 L of ${\text{PH}}_3$, measured at STP, forms, what is the percent yield?
