44Given the equation representing a reaction at equilibrium :2SO2(g) + O2(g) ==> 2SO3(g) + heat

Which change causes the equilibrium to shift to the right?

(1) adding a catalyst

(2) adding more O2(g)

(3) decreasing the pressure

(4) increasing the temperature

Verified Answer :

(2) Adding more O2(g) would shift the equilibrium to the right because a higher concentration of oxygen is offered than its initial position, therefore more products have to be yielded to maintain equilibrium.
