Consider the following system at equilibrium where H° = -198 kJ/mol, and Kc = 34.5 , at 1150 K.

2 SO2 (g) + O2 (g)  2 SO3 (g)

When 0.10 moles of SO3 (g) are added to the equilibrium system at constant temperature:

The value of Kc 

 



The value of Qc 

 

 Kc.

The reaction must

run in the forward direction to restablish equilibrium.
run in the reverse direction to restablish equilibrium.
remain the same.  It is already at equilibrium.



The concentration of O2 will 

 
Expert Solution
Step 1 Given

Given conditions when system at equilibrium 

H° = -198 kJ/mol 

Kc = 34.5

T = 1150 K.

2 SO2 (g) + O2 (g)  2 SO3 (g)

0.10 moles of SO3 (g) are added to the equilibrium system at constant temperature.
