Consider the following reactions at equilibrium and determine which of the indicated changes will cause the reaction to proceed to the right.
(1) CO(g) + 3H2(g) ⇋ CH4(g) + H2O(g) (add CH4)
(2) N2(g) + 3H2(g) ⇋ 2NH3(g) (remove NH3)
(3) H2(g) + F2(g) ⇋ 2HF(g) (add F2)
(4) BaO() + SO3(g) ⇋ BaSO4() (add BaO)
(a) 2, 3 (b) 1, 4 (c) 2, 4 (d) 2, 3, 4
