# Question #168d2

May 26, 2017

Statement C is false.

#### Explanation:

Let's take a look at the different options:

A
You can see entropy as the amount of disorder in a system. Therefore a gas has more disorder than a solid and will, therefore, have a higher entropy. This statement is true.

B
The second law of thermodynamics states that the entropy of the universe will always increase. This statement must therefore be true.

C
The original question was cut off by limited space in the title, but this option should probably be false. I image the option was something like:
Any event that is accompanied by an increase in the entropy of the system will be spontaneous.
This is false since a reaction can take place spontaneously when the entropy is decreasing! Remember that a reaction takes place spontaneously when the Gibbs free energy is negative:

$\Delta G = \Delta H - T \times \Delta S$
If the entropy is sufficient negative, the Gibbs free energy can be negative and therefore the reaction proceeds spontaneously.

Statement C is false.
