Question
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.)
All spontaneous reactions occur quickly.
The energy of the universe is constant; the entropy of the universe increases.
If a process increases the randomness of the particles of a system, the entropy of the system increases.
All systems become more disordered spontaneously.
All spontaneous processes release heat.
Both Ssys and Ssurr must equal zero at equilibrium.
Explanation / Answer
All spontaneous reactions occur quickly ..> false! never confuse kinetics with equilibrium! example...oxidation of metal!
The energy of the universe is constant; the entropy of the universe increases. --> True, at least for thermodynamic processes
If a process increases the randomness of the particles of a system, the entropy of the system increases. }True, if chaos is created, disorder increases, then Entropy increases
All systems become more disordered spontaneously --> False, this is only true for some processes, not all
All spontaneous processes release heat --> False, since some process require heat
Both Ssys and Ssurr must equal zero at equilibrium. --> False only that of the system
