QUESTION 18 Consider the following reversible reaction equation: 2502(g) + O2(g) → 2503(g) Ka = 1.2 x 10 Complete the following sentences (a-e) by selecting the best choice from the dropdown menus. a) This is an example of a equilibrium b) At equilibrium, this system will contain mostly c) If more SO2 is added to this system at equilibrium, the reaction will shift towards the d) If oxygen gas is removed from this system at equilibrium, the reaction will shift towards the e) If the volume of this system at equilibrium is increased, the reaction will shift towards the

Answer 1

2502(g) + O2 g) - 2503 (g) Ke 162x103 3 ket of oz decreases. To counter this eqceilibr- a) homogenous equilibrium If all species in equilibrium are in same phase (here gas phase) then et is homogenous a equilibrium. b) since, ke is higher than & the reaction is product favoured. [sog [Solog So cat equilibrium, systers will contain mostly So3 c) right 80g is added, the concentra- tion of so increase According to ke Chatlier Bonciple, system will oppose this. So reaction shifts to right, decreasing sog. left When og is removed, concentration right. when d)
