chemical kinetics
the area of chemistry concerned with reaction rates and the sequence of steps by which reactions occur

To describe a reaction rate, we must specify __. What is the rate?
 how fast the concentration of a reactant or a product changes per unit time
 rate= concentration change/ time change

reaction rate
 either the increase in the concentration of a product per unit time or as the decresae in the concentration of a reactant per unit time
 rate=delta[x]/ deltat

What are units for rates
Molar per second M/s

Why do we define reaction rate in terms of concentration (moles per liter) rather than moles?
because we want the rate to be independent of the scale of the reaction

The steeper the slope of the hypotenuse, the __
faster the rate

Reaction rate is defined as a __
positive quantity

The general rate of a reaciton equals
the rate of consumption of a reactant or formation of a product divided by its coefficient in the balanced chem equation

The slope of the tangent to a concentrationversustime curve at a time t is called the __ at that particular time. The instantaneous rate at the beginning of a rate (t=0) is called the __.
 instantaneous rate
 initial rate

what is the rate law?
rate=  delta[A]/ deltat= k[A]^m[B]^n

What does an exponent of one indicate?
the rate depends linearly on the concentration of the corresponding reactant

What does m=0 mean?
the rate is independent of the concentration of A because any number raised to the zeroth power equals one

If m is negative, __
the rate decreases as [A] increases

The values of the exponents m and n determine the __ with respect to A and B, respectively. The sum of teh exponents (m+n) defines the __.
 reaction order
 overall reaction order

The values of the exponents in a rate law must be determined by __; they cannot be deduced from the __ of the reaction.

One method of determining the values of the exponents in a rate lawthe __is to carry out a series of experiments in which the initial rate of a reaction is measured as a function of different sets of initial concentrations.
method of initial rates

first order reaction
one whose rate depends on the concentration of a single reactant raised to the first power

What is the integrated rate law?
ln[A]t/[A]0= kt
[A]0 is initial time concentration

A graph of ln [A] versus time is a __ having a slope of __. The value of hte rate constant is simply equal to __.
 straight line
 m=k
 (Slope)

First order reaction graphs?
the exponential decay is the same for every interval
