Section 13.1- Introduction to Chemical Kinetics Flashcards
describes a change in some quantity over time
rate
we may define reaction rate by the equation
reaction rate=
change in molarity/ time for change=
delta M/ delta t
the study of rates of reaction and the pathway taken during the reaction
chemical kinetics
the rate is often measured over a relatively short interval immediately after the reactants are combines; this is known as the
initial rate of reaction
when talking about concentration in an equation, put the thing concentrated in
brackets
from the _____________, we know that gas molecules are in constant motion
kinetic theory of matter
as time increases, the reactants will _________________ and the products will ________________
concentration of reactants DECREASE
concentration of the products INCREASE
rate = delta [?] / delta t
states that the greater the frequency and the greater the energy of collision between reactant particles, the greater the rate of reaction
collision theory (comes out of kinetic theory of matter)
the more particles are able to hit each other, that faster a reaction will be; affects that rate of reaction
- higher temperature, more collisions
the reaction rate of most reactions depends on the
positioning of the molecules – their orientation– when they collide
only a ___________________ will break the bonds and form new bonds
favorable collision
Chemical kinetics is the study of the
- Rates of reaction
- Pathway taken to get there
