Principle: The hydrolysis of an ester occurs according to the equation: The following rate equation is applicable to the above reaction: Rate [Ester] [H 2 O] Since [H 2 O] remains constant,
WebOrder of Molecularity The molecularity of an elementary reaction is the number of reactant particles (atoms, molecules, free radicals, or ions) that are involved in each individual chemical event. From: Encyclopedia of Physical Science and Technology (Third Edition), 2003 View all Topics Add to Mendeley About this page Apoptosis WebAnswer: Molecularity is number of molecules participate in a reaction. Order is the experimental quantity. On the other way order is the no of molecules which approaches at the same time to form transition state (this consideration is for slowest step).
