Select the BEST definition for entropy. Select one: a. stored energy in a substance that is exchanged as heat during a reaction (at constant pressure). b. tendency for a substance to achieve maximum disorder (i. e., randomly distribute). c. state of balance between a forward and a reverse reaction. d. ability of an atom to attract electrons for bonding.

b. tendency for a substance to achieve maximum disorder (i.e., randomly distribute).

Explanation:

Entropy can be defined as the tendency for a substance to achieve maximum disorder (i.e., randomly distribute).

This ultimately implies that, entropy is a thermodynamic quantity that measures the degree of maximum order or randomness of a system.

The S.I unit used for the measurement of the degree of maximum order or randomness of a system is Joules per Kelvin (JK¯¹). An example of entropy is the mixing of ideal gases.
