Fundementals of Reactions Kinetics Flashcards
1
Q
what exactly is a chemical reaction?
A
a change in composition of a mixture of chemical substances- from reactants to products, this is done via a change in arrangement of atoms, disintegration or combination, atom interchange…
NOTE: The number of atoms in reactants =no. of atoms in products
2
Q
define reaction mechanism
A
minimum set of reactions required to explain the experimental observation
3
Q
‘Radicals’
A
very reactive group of atoms that behave as a unit in a number of compounds e.g CH3, CHO, OH, HO2
Reactions with these occur fast
4
Q
chain reaction
A
a radical consumed in one reaction is regenerated in a following reaction
5
Q
Autocatalysis
A
the rate of the reaction accelerated as the reaction progresses
Often when one or more radical is produced
