‘Connubial’ relates to which type of relationship?
Open relationship Open relationship An open relationship is an intimate relationship which is consensually non-monogamous. This term may sometimes refer to polyamory, but it is often used to signify a primary emotional and intimate relationship between two partners who agree to have sexual relationships but not romantic relationships with other people. The nature of the openness in the relationship, including what outside sexual contact is permissible, varies widely. Open relationships include any type of romantic relationship (dating, marriage, etc.) that is open. The concept of an open relationship has been recognized since the 1970s. To a large degree, open relationships are a
Free-energy relationship rate constant for a reaction on which the catalyst operates. The Hammett equation predicts the equilibrium constant or reaction rate of a reaction from a "substituent constant" and a "reaction type constant". The Edwards equation relates the nucleophilic power to "polarisability" and "basicity". The Marcus equation is an example of a quadratic free-energy relationship (QFER). IUPAC has suggested that this name should be replaced by linear Gibbs energy relation, but at present there is little sign of acceptance of this change. The area of physical organic chemistry which deals with such relations is commonly referred to as 'linear free-energy relationships'.
