The rod initially has a mass of 1460g and the mole fraction, Ask an Expert

Academics

A chamber contains a heated silicon rod, and a mixtyre of high purity trichlorosilane mixed with high purity hydrogen that is passsed over the rod. Pure silicon(EGS-electronic grade Silicon) deposits on the rod as a polycrystalline solid. (Single crystals of Si are later made by subsequently melting the EGS and drawing a single crystal from the melt). THe reaction is

H2 (g) + SiHCl3 ........> Si (s) + 3HCl (g)

The rod initially has a mass of 1460g, and the mole fraction of H2 in the exit gas is 0.223. The mole fraction of H2 in the feed to the reactor is 0.580, and the feed enters at the rate of 6.22kg-mol/hr. What will be the mass of the rod at the end of 20 minutes?
