Which step is rate determining?

The rate determining step The overall reaction rate is determined by the rates of the steps up to (and including) the slowest elementary step. The slowest step in a reaction mechanism is called the rate determining or rate limiting step.

What is second order reaction in chemistry?

Definition of second-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 unit of K in 2nd order reaction?

As an example, for a first order reaction, k has the units of 1/s and for a second order reaction, units of 1/M.s.

What is first and second order reaction?

Key Terms. 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.

Which factor is present in second order reaction?

A 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 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.
