One advantage of the Kelvin system is that it is impossible to have temperatures below zero.

(A) True

(B) False

Identify the following statements as true or false. (Use the drop-down menu and select "True" or "False" for each. You must get all 6 correct.)
True False Both ΔS_sys and ΔS_surr must equal zero at equilibrium.
True False All systems become more disordered spontaneously.
True False If a process decreases the randomness of the particles of a system, the entropy of the system increases.
True False All spontaneous reactions occur quickly.
True False All spontaneous processes release heat.
True False The energy of the universe is constant; the entropy of the universe increases.

True or False: PO43? is the formula for the conjugate acid ofHPO32?.
True or False
False

Decide if the following statements are true or false.

True False The weaker the acid, the stronger the conjugate base.

True False The K_a equilibrium constant always refers to the reaction of an acid with water to produce the conjugate base of the acid and the hydronium ion.

True False Strong acids are assumed 100% dissociated in water.

True False The conjugate base of a weak acid is a strong base.

True False As a solution becomes more basic, the pOH of the solution increases.

True False As the K_b value for a base increases, base strength increases.
