2. Titanium (III) chloride a substance used in catalyst for preparing polyethylene, is made by a high-temperature reaction of TiCl4 vapor with H2:

2 TiCl4 (g) + H2 (g) ----> 2 TiCl3 (s) + 2HCl (g)

(a) How many grams of TiCl3 will be produced if 155 L of H2 at 435 degrees Celsius and 795 mmHg pressure react with excess TiCl4?
(b) How many liters of HCl gas at STP will result from the reaction described in part (a)?
