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.)
True False The energy of the universe is constant; the entropy of the universe increases.
True False All systems become more disordered spontaneously.
True False If a reaction is spontaneous, the reverse reaction is non-spontaneous.
True False The boiling of water at 105°C and 1 atm is a spontaneous process.
True False If a process increases the randomness of the particles of a system, the entropy of the system increases.
True False Both Ssys and Ssurr must equal zero at equilibrium.
Explanation / Answer
True:
The energy of the universe is constant; the entropy of the universe increases.
If a reaction is spontaneous, the reverse reaction is non-spontaneous. Because in spontaneous process energy is released so in the reverse reaction Energy will be utilized.
The boiling of water at 105°C and 1 atm is a spontaneous process.
If a process increases the randomness of the particles of a system, the entropy of the system increases. Because Entropy itself defines it is a measure of Randomness.
False:
Both Ssys and Ssurr must equal zero at equilibrium. since at equilibrium Ssys = Ssurr
All systems become more disordered spontaneously. If enegy of the system changes then entropy changes but not spontaneously
