What is the effect of entropy on spontaneous and non_spontaneous reactions?

Which of the following statements is true of spontaneous reactions?

Is each statement true or false? If false, correct it.

(a) All spontaneous reactions occur quickly. 

(b) The reverse of spontaneous reaction is nonspontaneous.

(c) All spontaneous processes release heat.

(d) The boiling point of water at 100 °C and 1 atm is spontaneous.

(e) If a process increases the freedom of motion of the particles of a system, the entropy of the system decreases.

(f) The energy of the universe is constant; the entropy of the universe decreases toward a minimum.

(g) All systems disperse their energy spontaneously.

(h) Both ΔS_sys and ΔS_surr equal zero at equilibrium.

Explain why during a spontaneous process the entropy change ofthe system could be negative. (How could the entropy of the systemdecrease for a spontaneous process?)
