Описание слайда:

Chemical kinetics studies the rate and mechanism of chemical reactions Chemical kinetics studies the rate and mechanism of chemical reactions

Слайд 3

Описание слайда:

In homogeneous reactions all the reactants exist in the same phase in which the reaction itself occurs. Na2CO3 + HCl ↔ NaHCO3 + NaCl Heterogeneous reactions take place only in the interphase. Fe + HClFeCl2 +H2

The dependence of the reaction rate on the concentration of reactants is described by the law of mass action discovered by N.Beketov, C. Guldberg and P. Waage in 1967: The dependence of the reaction rate on the concentration of reactants is described by the law of mass action discovered by N.Beketov, C. Guldberg and P. Waage in 1967: «At constant temperature the rate of chemical reaction is in direct proportion to the product of reactant concentrations in the degree of their stoichiometric coefficients».

Описание слайда:

Arrenius Equation establishes a connection between the reaction rate constant, activation energy and temperature: e is base of natural logarithm; R is universal gas constant (8.314 J / mol · K); T is absolute temperature, K; A is pre-exponential factor.

Описание слайда:

Catalysis is the change of chemical reactions rate under the influence of substances, the amount and nature of which, after completion of the reaction are the same as before the reaction. Catalysis is the change of chemical reactions rate under the influence of substances, the amount and nature of which, after completion of the reaction are the same as before the reaction. Catalyst is a substance that influences the rate of chemical processes without changing its own chemical composition.

Enzymes are catalysts of the chemical reactions in the body. An enzyme is a protein that catalyses a chemical reaction by lowering the activation energy.
