6.1 Reaction Rates Flashcards
chemical kinetics
the area of chemistry that deals with rates of reactions
reaction rate
the change in concentration
of a reactant or a product of a chemical
reaction per unit time
average reaction rate
the change in reactant or product concentration over a given time interval
instantaneous reaction rate
the rate of a chemical reaction at a single point in time
Reaction rates are not ________; they ________ as the reaction proceeds.
constant; change
By convention, reaction rates are always expressed as ______ values.
positive
Reaction kinetics – the study of:
Rates of reactions
Factors that affect the rate of a reaction
How reactions occur
Rate of reaction is determined by measuring the rate of formation of a ________ or the rate of __________ of a reactant
product; disappearance
Remember that during a chemical reaction, bonds between atoms are _______ and _________
broken; re-formed
If a reactant is disappearing, rate will be _______.
negative
If a product is appearing, rate will be ________.
positive
