The Speed and Direction of Chemical Reactionstaneous reactions. Others can be quite slow. The chemical reaction that converts sweet grape juice into alcohol takes several weeks, the souring of milk one or two days. Epoxy resin adhesives such as ‘Araldite’ take several hours to harden. Reactions of substances called ‘linoleic esters’ take many

Large Moleculesins 161 atoms. In spite of their size, each molecule has a precise structure and a definite position for each one of its atoms. Other naturally occurring molecules are exceptionally large. Starch molecules contain between 1500 and 150 000 atoms; rubber molecules between 13 000 and 65 000 atoms. In t
