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
This Is Only a Test Only a Test" isn't without its moments of awkwardness. Whether it's piano-heavy power ballads ('College'), spoken-word verses written as diary entries ('Diary of a Teen Tragedy') or five-minute electronic tracks about not being able to participate in P.E. class ('Excuse Me, Coach'), Smoking Popes occasionally veer off their tried and true template of catchy, soulful pop-punk, and do so with mixed results." However, he noted that "there are still plenty of hooks to be found on the album, especially it its loaded first half", comparing the band to Weezer and calling the album "a mostly successful experiment."
