Elementary reaction is referred to as a unimolecular step
False
Chemical kinetics is the study of rate of chemical processes
True
Termolecular step can occur at any condition of reaction.
False
When may the termolecular step occur?
A termolecular step may occur under conditions of extremely high pressure
Elementary processes contain a transition between two atomic or molecular states separated by a potential barrier.
True
What does stoichiometry coefficient mean in a chemical equation?
A stoichiometric coefficient refers to the number of moles of each reactant or product appearing in the equation.
The reaction rate can be determined from any reactant and its stoichiometric coefficient.
True
The rate of any chemical reaction decreases with passage of time as the concentration of reactants decreases.
Not given
What is an elementary step?
An elementary step is a single-step process in a chemical reaction, which usually involves either a single reactive collision between two molecules.......
What is another name for the order of the reaction with respect to a reactant?
The power a particular concentration is raised to is the order of the reaction with respect to that reactant.
The order of a reaction is always equal to the sum of stoichiometric coefficients of reactant in the balanced chemical equation for a reaction.
False
The activation energy of the process is constituted from the potential barrier.
True
You are eggcellent !!
you are eggstremely cute
What is the rate law in chemical kinetics?
The rate law is an expression relating the rate of a reaction to the concentrations of the chemical species present, including reactants, products, and catalyst
In order to have a unique reaction rate, how can we deal with the reaction having different substances with different stoichiometric coefficients?
The reaction rate is defined as the rate of change of the concentration of a reactant or product divided by its stoichiometric coefficient. A negative sign is..
What does chemical kinetics deal with?
Chemical kinetics deals with the rates of chemical processes
According to the text, which parameter determines the rate of reaction?
The activation energy determines the rate of a reaction.
Is the overall order of a reaction always an integer?
No, the overall order does not have to be an integer
What is the overall order of a reaction?
The overall order is the sum of the powers.
The reaction which has low value of activation energy will occur very fast.
True
The rate constant of reaction always depends on the initial concentration of reactants.
False
