How Do You Spell RIDEAL-WALKER METHOD?

Pronunciation: [ɹˈa͡ɪdə͡lwˈɔːkə mˈɛθəd] (IPA)

The Rideal-Walker method, used in chemical engineering to determine surface area, is pronounced /ɹaɪˌdiːl ˈwɔːkə ˈmɛθəd/. The spelling of this term can be broken down using the International Phonetic Alphabet, which uses symbols to represent the sounds of speech. The first part, Rideal, is pronounced with a long "i" sound, followed by a voiced dental fricative "th" sound and a schwa. Walker is pronounced with a long "a" sound, a voiced velar stop, and an "er" sound. Together, these words form Rideal-Walker, pronounced as one compound word with stress on the first syllable.

RIDEAL-WALKER METHOD Meaning and Definition

  1. The Rideal-Walker method, also known as the Rideal-Walker coefficient determination or the Rideal-Walker technique, is a chemical analysis technique used to determine the rate constants of reactions occurring between gases and solid surfaces. It is widely applied in the field of surface chemistry.

    In this method, a solid sample is placed in a vessel or flow system, and a gas is passed over or through the solid. The reaction between the gas and the solid surface is monitored, typically by measuring the decrease in gas concentration or pressure over time. The reaction is assumed to follow a first-order kinetics, meaning that the rate of reaction is directly proportional to the concentration or pressure of the gas.

    The Rideal-Walker method involves plotting the logarithm of the reaction rate constant against the reciprocal of the absolute temperature. This linear plot enables extrapolation to determine the activation energy, a crucial parameter in characterizing the reaction mechanism.

    The method is named after Cyril Cyriloff Ridéal and Gilbert Thomas Walker, who independently developed the technique in the early 20th century. Rideal and Walker recognized the importance of surface chemistry in many industrial processes and sought to provide a quantitative approach to understanding gas-surface reactions.

    The Rideal-Walker method has found applications in various fields, including catalysis, materials science, environmental science, and chemical engineering, where the interactions between gases and solid surfaces play a vital role.

  2. A method of standardization of disinfectants by a comparison of the strength of a disinfectant necessary to kill the typhoid bacillus in a definite time with that of a solution of carbolic acid which will accomplish the same thing in the same time.

Etymology of RIDEAL-WALKER METHOD

The Rideal-Walker method is named after the scientists who developed it, namely Eric Rideal and Majory Stephenson Walker. Eric Rideal was a British chemist and surface scientist, while Marjory Stephenson Walker (later known as Marjory Stephenson) was a British microbiologist and biochemist. Together, they collaborated on the development of the Rideal-Walker method, which is a technique used in physical chemistry for determining the surface area of solids.
