Track listing

Catalysis

Catalysis (/kəˈtælᵻsᵻs/) is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst (/ˈkætəlᵻst/). With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.

Technical perspective

In the presence of a catalyst, less free energy is required to reach the transition state, but the total free energy from reactants to products does not change. A catalyst may participate in multiple chemical transformations. The effect of a catalyst may vary due to the presence of other substances known as inhibitors or poisons (which reduce the catalytic activity) or promoters (which increase the activity). The opposite of a catalyst, a substance that reduces the rate of a reaction, is an inhibitor.

Catalyzed reactions have a lower activation energy (rate-limiting free energy of activation) than the corresponding uncatalyzed reaction, resulting in a higher reaction rate at the same temperature and for the same reactant concentrations. However, the detailed mechanics of catalysis is complex. Catalysts may affect the reaction environment favorably, or bind to the reagents to polarize bonds, e.g. acid catalysts for reactions of carbonyl compounds, or form specific intermediates that are not produced naturally, such as osmate esters in osmium tetroxide-catalyzed dihydroxylation of alkenes, or cause dissociation of reagents to reactive forms, such as chemisorbed hydrogen in catalytic hydrogenation.

Public Relations Exercise

Public Relations Exercise were a Leicester, England based post-hardcore/alternative rock group. A five-piece combining aspects of screamo and math rock, layered with penetrative and socially observant lyrics.

History

The band began as a product of the development of bedroom songwriters Martin Smith and Lloyd Carter. From an early age, they worked on various projects with local drummer Danny Star, and with the later addition of Irish-born bassist, Tiernan Welch, and guitarist, Spencer Lee, their line-up was finalised in September 2005. The name is taken from the inlay of Radiohead's second album, The Bends.

In their short history; Public Relations Exercise played with acts including Youthmovies, 65daysofstatic, Foals and many others. After demoing material for some time, the band recorded their debut single 'Subteniente', at Far Heath Studios with producer Angus Wallace (The Fall, The Prodigy) in 2007, which was released as a through Nottingham based Field Records in conjunction an extensive UK tour with ex-Million Dead frontman Frank Turner and London Hardcore outfit Score One For Safety.
