DRILL 1
Question Type A
Questions 1–3 refer to the following.
(A) Ca2+(aq) + CO 3 2−(aq) CaCO 3 (s)
(B) N 2 (g) + 2O 2 (g) 2NO 2 (g)
(C) 4NH 3 (g) + 5O 2 (g) 4NO(g) + 6H 2 O(g)
(D) H 2 (g) + I 2 (g) 2HI(g)
(E) Na 2 O 2 (s) + H 2 O(l) NaOH(aq) + H 2 O 2 (aq)
- Reaction rate can be increased by increasing the surface area of
reactants
- Increasing system pressure by decreasing reaction volume shifts
equilibrium to the right
- Impossible to increase rate of reverse reaction by increasing the
concentration of reactant(s)
