Homogeneous catalysis heterogeneous catalysis is the petrochemical alkylation process, where the liquid reactants are immiscible with a solution containing the catalyst. Heterogeneous catalysis offers the advantage that products are readily separated from the catalyst, and heterogeneous catalysts are often more stable and degrade much slower than homogeneous catalysts. However, heterogeneous catalysts are difficult to study, so their reaction mechanisms are often unknown. Enzymes possess properties of both homogeneous and heterogeneous catalysts. As such, they are usually regarded as a third, separate category of catalyst. Homogeneous catalysis In chemistry, homogeneous catalysis is catalysis in a solution by a soluble catalyst. Homogeneous catalysis refers
A Woman Is a Weathercock Collier in 1829. An edition based on a copy of the first quarto in the Folger Shakespeare Library was published in 1950, edited by William Peery. Commentators like Peery have called "A Woman is a Weathercock" a remarkable achievement for a first-time dramatist who was not yet 22 – and ascribed this to the practical experience Field had amassed performing on the stage since the age of 11 or 12. Collier said: ""A Woman is a Weathercock" and its sequel "Amends for Ladies" are the productions of no ordinary poet: in comic scenes Field excels Massinger ... and in those
