Expert Solution

Step 1

Given reaction at equilibrium;

SO_{2 (g)}+ NO_{2 (g)}<-----> SO_{3 (g)}+ NO_(g)

In 1.0 L flask,

Initial moles of SO_{2 (g)}= 2.00 moles

Initial moles of NO_{2 (g)}= 2.00 moles

At equilibrium, moles of NO_(g)formed = 1.41 moles

ICE table ;

	SO_{2 (g)}	NO_{2 (g)}	SO_{3 (g)}	NO_(g)
Initial conc (in moles)	2.0	2.0	0	0
Change in conc (in moles)	-1.41	-1.41	+1.41	+1.41
Equilibrium concentration (in moles)	+0.59	+0.59	+1.41	+1.41
