Question

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 35oC 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 35oC will be obtained if the percent yield of the reaction is 93.1%?
