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.)
If a process increases the randomness of the particles of a system, the entropy of the system increases.
If a reaction is spontaneous, the reverse reaction is non-spontaneous.
All spontaneous processes release heat.
All systems become more disordered spontaneously.
Both ?Ssys and ?Ssurr must equal zero at equilibrium.
The entropy of the universe is constant the energy of the universe decreases towards a minimum.
