The integrated rate law for the second-order reaction A → products is
1/[A]_t = kt + 1/[A]_0
. Because this equation has the form y = mx + b, a plot of the inverse of [A] as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to k.
What is the equation for a second order reaction?
Second order reactions can be defined as chemical reactions wherein the sum of the exponents in the corresponding rate law of the chemical reaction is equal to two. The rate of such a reaction can be written either as
r = k[A]
2
, or
as r = k[A][B].
What is the rate constant of second order reaction?
| Zero-Order Second-Order | rate law rate = k rate = k[A] 2 | units of rate constant M s − 1 M − 1 s − 1 | integrated rate law [ A ] = − k t + [ A ] 0 [ A ] = − k t + [ A ] 0 1 [ A ] = k t + ( 1 [ A ] 0 ) 1 [ A ] = k t + ( 1 [ A ] 0 ) | plot needed for linear fit of rate data [A] vs. t 1 [ A ] vs. t |

What is integrated rate equation?
=> [A] = -kt + [A]0
. The above equation is known as integrated rate equation for zero order reactions. We can observe the above equation as an equation of straight line with concentration of reactant on y-axis and time on x-axis. The slope of the straight line signifies the value of rate constant, k.
What is a 2nd order reaction?
: a chemical reaction in which the rate of reaction is proportional to the concentration of each of
two reacting
molecules — compare order of a reaction.
What is the example of second order reaction?
Reactions in which reactants are identical and form a product can also be second order reactions. Many reactions such as
decomposition of nitrogen dioxide, alkaline hydrolysis of ethyl acetate, decomposition of hydrogen iodide
, formation of double stranded DNA from two strands etc.
Which is the example for second order level?
For example, you can think of this
as I’m hungry so let’s eat a chocolate bar
. Second-order thinking is more deliberate. It is thinking in terms of interactions and time, understanding that despite our intentions our interventions often cause harm.
What is meant by second order?
Filters
. (mathematics, logic) Describing the second in a numerical sequence of models, languages, relationships, forms of logical discourse etc. adjective.
Which factor is present in second order reaction?
second order reaction is a type of chemical reaction that depends on
the concentrations of one-second order reactant or two first-order reactants
. This reaction proceeds at a rate proportional to the square of the concentration of one reactant, or the product of the concentrations of two reactants.
What is 2nd order kinetics?
second-order kinetics. A term
describing the reaction rate of a chemical reaction in which the rate is proportional to the product of the concentrations (in moles) of two of the
reactants (also called bimolecular kinetics), or to the square of the molar concentration of the reactant if there is only one.
What is the use of integrated rate equation?
On the other hand, integrated rate laws express the
reaction rate as a function of the initial concentration and a measured (actual) concentration of one or more reactants after a specific amount of time (t)
has passed; they are used to determine the rate constant and the reaction order from experimental data.
What is the difference between rate law and integrated rate law?
The key difference between differential rate law and integrated rate law is that differential rate law
gives the rate of a chemical reaction as a function of the change in concentration of one or more reactants during a particular time period
whereas integrated rate law gives the rate of a chemical reaction as a …
Is photosynthesis a second order reaction?
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage,
the light-independent reactions
use these products to capture and reduce carbon dioxide.
What is the difference between first and second order reactions?
A first-order reaction rate depends on the concentration of one of the reactants. A second-order reaction rate is
proportional to the square of the concentration of a reactant or the product of the concentration of two
reactants.
What is the integrated rate law for a second order reaction?
The integrated rate law for the second-order reaction A → products is
1/[A]_t = kt + 1/[A]_0
. Because this equation has the form y = mx + b, a plot of the inverse of [A] as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to k.
