Answer #1

H2(g)+I2(g)→2HI(g)

total no of moles of reactant and total no of products are same.No change in equilibrium with pressure changes

NO(g)+O3(g)→NO2(g)+O2(g)

total no of moles of reactant and total no of products are same.No change in equilibrium with pressure changes

2SO3(g)→2SO2(g)+O2(g) >>>>answer

When pressure is decreases no of moles or volume increases side favor the reaction. The equilibrium shift to right decrease pressure.

CO(g)+H2O(g)→CO2(g)+H2(g)

Total no of moles of reactant and total no of products are same.No change in equilibrium with pressure changes
