What is a trait of chemical equilibrium?
a.
equilibrium is reached through catalyst reaction
c.
a system "at equilibrium" appears to have a positive charge
b.
equilibrium always happens at the same point in the reaction no matter where you start
d.
equilibrium is always at the same point regardless of the reagents involved in the reaction

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
