I'm super lost on how to solve this problem, I know we have to use an ice table to find unknown variables but Im not sure how to go about solving for all of the parts. Please explain your answer and show all the steps and rationale behind solving this problem. Its greatly appreciated! Thank you!!

2. Gallium arsenide (GaAs) is an important eonlpomld to the eleen‘onies industry. It is produced
in the following reaction between arsine (Asﬂg) and trinleﬂlyl gallium (Ga(CH3)3) : 21ng (g) + Ga(CH3)3 (g) a GaAs (s) + 3 cm (g) If this reaction is initiated at 760°C between 1.00 atm of Ga(CH3)3 and 1.00 atm of ASH3 in a
rigid 1L vessel, and 1.00 X 10—5 ml of AsH; is left to dispose of at the end of the reaction?
what is the equilibrium constant, KP? A) 2.21 2: MI2
E) 3.32 x 107
C) 4.25 x 11)6 D) 1.42 2:10‘5
B) 2.20 2:1011
