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.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
