Silane (SiH₄) is the silicon analogue of methane (CH₄). It is prepared industrially according to the following equations:

Si(s) + 3HCl(g) → HSiCl₃(l) + H₂(g) 4HSiCl₃(l) → SiH₄(g) + 3SiCl₄(l)

a. If 156 mL of HSiCl₃ (d = 1.34 g/ mL) is isolated when 15.0 L of HCl at 10.0 atm and 35^oC is used, what is the percent yield of HSiCl₃?

b. When 156 mL of HSiCl₃ is heated, what volume of SiH₄ at 10.0 atm and 35^oC will be obtained if the percent yield of the reaction is 93.1%?
