Question

1.The reaction 2 NOCl22KcWhich one statement about this reaction is FALSE?Select one:

(g)2 NO(g) + Cl(g)  has = 0.0150 at 115°C.

a.   At higher temperatures, Kc for this entropically-favoured reaction is larger than 0.0150.

b.   The Kp for this reaction at 115°C is 0.478, because Δngases is +1.

c.   Adding Ar(g) will not affect this equilibrium, even though the pressure in the container will increase.

d.   If 0.225 M NOCl2(g), 0.150 M NO(g) and 0.375 M Cl2(g) are placed in a closed container at 115°C, the reaction will proceed backwards until equilibrium is established.

e.   If the container volume is decreased, Q < K, so the equilibrium shifts right.


2.Which statement correctly describes Vitamin C (structure shown)? (refer to picture)


Select one:

a.   has 4 hydrogen-bond acceptor atoms & 8 hydrogen-bond donors

b.   has 6 hydrogen-bond acceptor atoms & 8 hydrogen-bond donors

c.   can engage in hydrogen bonding only when dissolved in water

d.   has 6 hydrogen-bond acceptor atoms & 4 hydrogen-bond donors

e.   has 4 hydrogen-bond acceptor atoms & 4 hydrogen-bond donors


3.Which one statement about aqueous solutions and suspensions is FALSE?

Select one:

a.   Gases are less soluble in warm water than in cold water, because dissolved gases have lower entropy.

b.   Water excludes hydrophobic solutes because fully surrounding them requires enthalpic sacrifice.

c.   In detergent micelles in water, the shell of "heads" interacts with water but the core of "tails" does not.

d.   The ΔS and ΔH for dissolving ionic solids involve several factors, so salt solubility is hard to predict.

e.   The larger the ion, the stronger the ion-dipole attractions the ion has with water molecules.
