Exam 1 Flashcards
Reaction rate equation
molarity/time
Initial Rate
Instantaneous rate observed as
close to the beginning of a reaction as possible
Average Rate
calculated rate over any time
interval
Instantaneous Rate
The rate at one particular
time
Chemical rate law
an equation relating the initial reactant concentrations
to the initial instantaneous reaction rate
reaction order
the exponent of the reactant in the rate law
overall reaction order
the sum of the exponents of all of the reactants in the rate law
Half life
the time required for the concentration of a reactant to decrease to ½ of its initial concentration
Second Order Reaction
rate depends on one reactant concentration raised to the second power or two reactants each first order
Dynamic Equilibrium
when two opposing processes occur at equal rates- so no net change in the appearance of a system
chemical equilibrium
rate of forward reaction equals the rate of the reverse reaction
homogenous equilibria
all reactants and products in the same phase
heterogeneous equilibria
not all reactants and products in the same phase
Strong bases
Group 1A metal hydroxides (LiOH, NaOH, KOH, RbOH, CsOH)
Heavy group 2A metal hydroxides [Ca(OH)2, Sr(OH)2, Ba(OH)2]
Environmental
all the things you experience through your senses
