In a Diels-Alder reaction with maleic anhydride, which isomer of 2,4-hexadiene would react fastest and slowest: (Z,Z), (Z,E), or (E,E)? Briefly explain.

The Attempt at a Solution
I am guessing that (Z,Z) reacts fastest and (E,E) reacts slowest, due to steric hinderence. Is my answer correct? If so, is my brief explanation manageable? Thanks.
The Diels-Alder reaction is a chemical reaction in which a diene (a molecule with two double bonds) reacts with a dienophile (a molecule with a double bond) to form a cyclic compound. It is commonly used in organic synthesis to create complex molecules.
The rate of the Diels-Alder reaction can be affected by several factors, including the nature of the diene and dienophile, temperature, solvent, and the presence of catalysts. These factors can either speed up or slow down the reaction.
The speed of the Diels-Alder reaction can vary depending on the reactants and conditions. In general, the reaction is considered to be relatively fast, with reaction times ranging from a few minutes to a few hours. However, the rate can be increased by using certain catalysts or by increasing the temperature.
To optimize the speed of the Diels-Alder reaction, chemists can carefully select the reactants, use a suitable solvent, and add a catalyst to speed up the reaction. Additionally, increasing the temperature and stirring the reaction mixture can also help to speed up the reaction.
While the Diels-Alder reaction is a versatile and useful tool in organic synthesis, it does have limitations. For example, the reaction may not be possible if the diene and dienophile are not compatible, or if the reaction conditions are not suitable. Additionally, the reaction may not proceed as quickly or efficiently as desired, which can be challenging when working with time-sensitive reactions.
