I need help with part B

Part A Phos gene (carbonyl chloride). Cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. Phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures CO(g) Cl2(g)E CoCl2(g) Carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 466 C At equilibrium, the concentrations were measured and the following results obtained Partial Pressure Gas (atm) 0.900 1.25 COC12 0.230 What is the equilibrium constant, Kp, of this reaction? Express your answer numerically K 0.204 Submit Hints My Answers Give Up Review Part Correct Deriving concentrations from data n Part A, you were given the equilibrium pressures, which could be plugged directly into the formula for K. In Part B however, you will be given initial concentrations and only one equilibrium concentration. You nust use this data to find all three equilibrium concentrations before you an apply the formula for K Part B The following reaction was performed in a sealed vessel at 712 C H2 (g) I2 (g) 2HI(g) Initially, only H2 and I2 were present at concentrations of CH2 3.50 MM and I2] 2.55M The equilibrium concentration of I2 is 0.0200M. WI is the equilibrium constant, KC, for the hat reaction at this temperature? Express your answer numerically reset shortcuts help Submit Hints My Answers Give Up Review Part

Explanation / Answer

given equilibrium concntration of I2=0.0200

so x=conversion=2.55-0.0200=2.53

so amount of H2 remaining at equilibrium = 0.97 M

So amount of HI formed is 2*2.53=5.06 M

Kc=HI^2/H2*I=5.06*5.06/0.97*0.02=1319.773
