gr adedA+( Pass Gu ar anteed)
Kinetics - answer the study of rates of reactions and how they are influenced by
certain factors
Influences Reactions Rates - answer Concentration, temperature, catalysts,
surface area
Temperature/Reaction Rate - answer Increase, higher temperature provides
higher kinetic energy
Catalyst/Reaction Rate - answer Increase, without being consumed
Surface Area/Reaction Rate - answer Increase, increased surface area of particles
increases reaction rate because solids only react at their surfaces (grinding solid
into fine powder)
Concentration/Reaction Rate - answer Increase, provides more reacting particles
to undergo reaction
Reaction Rate - answer Increase in molar concentration of product per unit of
time or the decrease in molar concentration per unit of time
, Reaction Rate Units - answer moles per liter per second (mol/L*s)
Reaction Rate Equation - answer Change in concentration/change in time
(products=positive, reactants=add negative sign)
Average Rate - answer Determined by using initial and final concentrations and
initial and final times so that the result measures the rate over the entire reaction
Instantaneous Rate - answer The change in concentration of reactants (or
products) divided by a very short period of time
Instantaneous Rate Decreases... - answer Decreases, as reaction proceeds,
concentration of reactant becomes smaller due to consumption of reactants as
reaction takes place
Early Instantaneous Rate - answer The change in concentration of reactants (or
products) divided by a very short period of time near the beginning of the
reaction
Late Instantaneous Rate - answer The change in concentration of reactants (or
products) divided by a very short period of time at the end of the reaction
Relative Values of Average Rate, Early Instantaneous Rate, and Late Instantaneous
Rate - answer The early instantaneous rate will be greater (most reactant) than
