Stereoisomers are defined as molecules with the same structural formula but a different arrangement of the atoms in space. Owing to the restricted rotation around a C=C double bond it is possible for alkenes to exist as stereoisomers if there are two different groups attached to each carbon atom in the double bond.

Therefore, the trans acid has the carboxyl group equatorial and the cis acid has it axial, as you have rightly pointed out. The difference in acidity is to do with the resulting solvation of the carboxylate group.
WebWe can name an alkene using the following steps: (1) Identify the longest carbon chain containing the double bond. (2) Number the carbons, ensuring the double bond gets the lowest possible number. (3) Include the double bond location as a prefix to the root name. (4) Add any substituents as prefixes, in alphabetical order if needed.
