Solution: Sulfur dioxide reacts with chlorine at 227°C: SO2(g) +Cl2(g) <—> SO2Cl2(g) Kp for this reaction is 5.1 x 10-2 atm-1. Initially, 1.00 g each of SO2 and Cl2 are placed in a 1.00 L reaction vessel. After 15 minutes, the concentration of SO2Cl2 is 45.5 μg/mL. You will determine if the system has reached equilibrium. First, what is Kc, (in L/mol)? (A μg is 10-6 g.) Next determine all initial concentrations. What is the initial sulfur dioxide concentration (in mol/L or M)? Determine all concentrations after 15 minutes. What is the chlorine concentration? What is Q after 15 minutes? 

Problem

Sulfur dioxide reacts with chlorine at 227°C: 

SO2(g) +Cl2(g) <—> SO2Cl2(g) 

Kp for this reaction is 5.1 x 10-2 atm-1. Initially, 1.00 g each of SO2 and Cl2 are placed in a 1.00 L reaction vessel. After 15 minutes, the concentration of SO2Cl2 is 45.5 μg/mL. You will determine if the system has reached equilibrium. First, what is Kc, (in L/mol)? (A μg is 10-6 g.) 

Next determine all initial concentrations. What is the initial sulfur dioxide concentration (in mol/L or M)? 

Determine all concentrations after 15 minutes. What is the chlorine concentration? 

What is Q after 15 minutes?
