Nowadays, However, We Recognize That Simultaneously With

The Well-known Fact That The Form Of A Specific Substance, E.g. Water, And Hence Its Properties Can Alter Without A Change In Composition Was Disposed Of By The Formal View That A Physical, Not A Chemical, Process Was Involved.

The Worst Manifestations Of Exhaustion Were Successfully Cured By A Long Period Of Rest But It Was Immediately Apparent To Me That I Had Lost Once And For All My Former Capacity For Carrying Out Experimental Work Until Physically Tired.

The Distinction Between The Old And The New Formulations Consisting In The Incorporation Of The Concept Of The Rate Of Chemical Reactions Is So Great That It Immediately Asserted Itself In The Objective Development Of Catalysis.

Nowadays, However, We Recognize That Simultaneously With The Typical Case Of A Chemical Reaction A Typical Case Of Catalytic Effect Had Been Studied Which Constitutes A Limiting Case.

In The First Quarter Of The Nineteenth Century The Experimental Proof For The Interdependence Of The Composition And Properties Of Chemical Compounds Resulted In The Theory That They Are Mutually Related, So That Like Composition Governs Like Properties, And Conversely.
