Question

19. The equilibrium expression for Kp for the reaction below is 203(g) -+ 302 (g) 3PO A) 2PO, 2PO 3PO 3PO 2Po, PO,2 PO,2 PO,3 PO, D) 20. The equilbrium constant for the gas phase reaction 2NH3 (g) N2 (g) + 3H2(g) is Keq = 230 at 300°C At equilibrium, A) products predominate B) reactants predominate C) roughly equal amounts of products and reactants are present D) only products are present E) only reactants are present 21. A Bronsted-Lowry acid is defined as a substance that A) increases Ka when placed in H20 8) decreases [H+1 when placed in H20 C) increases (OH] when placed in H20 D)acts as a proton acceptor E) acts as a proton donor 22. Which one of the following is a Brönsted-Lowry acid? A) (CH3)3NH* B) CH3COOH C) HF D) HNO2 E) all of the above

Explanation / Answer

19. 2O3(g) --------> 3O2(g)
    Kp = P^3 O2/P^2 O3
A. Kp = P^3 O2/P^2 O3
20. 2NH3(g) --------> N2(g) + 3H2(g) Keq = 230
D. only products are present
21. Bronsted - lowry acid: A substance which donate proton is called Bronsted -lowry acid
E. acts as a proton donor
22. E. all of the above
