Section 13.1- Introduction to Chemical Kinetics

Question 1

describes a change in some quantity over time

Answer 1

rate

Question 2

we may define reaction rate by the equation

Answer 2

reaction rate=
change in molarity/ time for change=
delta M/ delta t

Question 3

the study of rates of reaction and the pathway taken during the reaction

Answer 3

chemical kinetics

Question 4

the rate is often measured over a relatively short interval immediately after the reactants are combines; this is known as the

Answer 4

initial rate of reaction

Question 5

when talking about concentration in an equation, put the think concentrated in

Answer 5

brackets

Question 6

from the _____________, we know that gas molecules are in constant motion

Answer 6

kinetic theory of matter

Question 7

as time increases, the reactants will _________________ and the products will ________________

Answer 7

concentration of reactants DECREASE
concentration of the products INCREASE

rate = delta [?] / delta t

Question 8

states that the greater the frequency and the greater the energy of collision between reactant particles, the greater the rate of reaction

Answer 8

collision theory (comes out of kinetic theory of matter)

Question 9

the more particles are able to hit each other, that faster a reaction will be; affects that rate of reaction

Answer 9

1. higher temperature, more collisions

Question 10

the reaction rate of most reactions depends on the

Answer 10

positioning of the molecules – their orientation– when they collide

Question 11

only a ___________________ will break the bonds and form new bonds

Answer 11

favorable collision
