Select all of the following statements that are true about entropy and the second law:

1. The higher the heat capacity of the system, the more microstates it contains.

2. When the ΔSsurr = - ΔSsys, the reaction will be spontaneous in the reverse direction.

3.A reaction that has a positive ΔSsys and a positive ΔSsurr will always be spontaneous, regardless of temperature.

4. When the ΔSsys is positive, the reaction will be spontaneous in the direction written.

5. When the ΔSuniv = 0, the system is at equilibrium.

6. Spontaneous reactions happen quickly.

7. If a spontaneous reaction has a negative ΔSsys, the change in the ΔSsurr must be positive and larger than the system value.

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 ΔSsys and ΔSsurr must equal zero at...
