_____ 4. Diluting concentrated sulfuric acid with water can be dangerous because the
temperature of the solution can increase rapidly. What are the signs of ∆H, ∆S, and ∆G for this
process
(A) ∆H < 0, ∆S < 0, ∆G < 0
(B) ∆H > 0, ∆S < 0, ∆G < 0
(C) ∆H < 0, ∆S > 0, ∆G < 0
(D) ∆H > 0, ∆S > 0, ∆G < 0
(E) ∆H > 0, ∆S < 0, ∆G > 0
_____ 5. For a chemical system, ∆G° and ∆G are equal when
(A) the equilibrium constant, K, equals 1.
(B) the equilibrium constant, K, equals 0.
(C) the system is at equilibrium.
(D) The reactants and products are in the gas phase.
(E) the reactants and products are in their standard states.
