Homogeneous catalysis Homogeneous catalysis In chemistry, homogeneous catalysis is catalysis in a solution by a soluble catalyst. Homogeneous catalysis refers to catalytic reactions where the catalyst is in the same phase as the reactants. Homogeneous catalysis applies to reactions in the gas phase and even in solids. Heterogeneous catalysis is the alternative to homogeneous catalysis, where the catalysis occurs at the interface of two phases, typically gas-solid. The term is used almost exclusively to describe solutions and often implies catalysis by organometallic compounds. The area is one of intense research and many practical applications, e.g., the production of acetic acid. Enzymes are
Lines Composed in a Wood on a Windy Day five and nine, as well as the erasures before "sunshine" and "above" suggest that the poem was written hastily. One interpretation by Winidred Gerin says that in the poem "emotion and expression have achieved a fusion as felicitous as it is rare in Brontë's writing, is probably the best poem she ever wrote, though not the most characteristic". The poem is based upon an actual experience of Brontë's. A note stating "Composed in the Long-Plantation on a wild bright windy day", was written in Anne Brontë's hand at the bottom of the manuscript and the "Long-Plantation" was identified by Edward
