Differbetween
the correct difference between first and second order reactions is that. The rate of a first-order reaction does not depend on reactant concentration, the rate rate of a second-order reaction does depend on reactant concentration.

What is the difference between first order and second order?
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 first and second order reaction?
second-order reaction: A reaction that depends on the concentration(s) of one second-order reactant or two first-order reactants. reaction mechanism: The step-by-step sequence of elementary transformations by which overall chemical change occurs.
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.
How do you know if its 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].
Is first order or second order faster?
A reaction being first order does not necessarily indicate that it is faster than a second order reaction, just that changing the concentrations of a reactant in the first order reaction has a less "drastic" effect on the rate than if you made that same concentration change to a second order reaction.
What is a 2nd order system?
A system whose input-output equation is a second order differential equation is called Second Order System. ... There are a number of factors that make second order systems important. They are simple and exhibit oscillations and overshoot. Higher order systems are based on second order systems.
What is second order reaction give example?
A second kind of second-order reaction has a reaction rate that is proportional to the product of the concentrations of two reactants. ... An example of the former is a dimerization reaction, in which two smaller molecules, each called a monomer, combine to form a larger molecule (a dimer).
How do you know if a reaction is zero order?
Zero-order reactions are typically found when a material that is required for the reaction to proceed, such as a surface or a catalyst, is saturated by the reactants. A reaction is zero-order if concentration data is plotted versus time and the result is a straight line.
What is the slope of a second order reaction?
For a first-order reaction, a plot of the natural logarithm of the concentration of a reactant versus time is a straight line with a slope of −k. For a second-order reaction, a plot of the inverse of the concentration of a reactant versus time is a straight line with a slope of k.
What is the rate constant for second order reaction?
Zero-Order Reactions
| 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] = −kt + [A]0 | 1[A]=kt+(1[A]0) |
| plot needed for linear fit of rate data | [A] vs. t | 1[A]vs.t t |
What does second order kinetics mean?
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.
