rate of kinetics

..

. Transition State explains the rate of reaction in term of formation of a transition state of reacting molecules. The formation of transition state requires energy of activation. Transition state theory connects kinetic rates with thermodynamic properties of reactants..

>Matter consists of molecules. These are the smallest particles, which are capable of free existence and retain all the chemical properties of the parent substance. The molecules are always in a state of random continuous motion. The molecules exert forces on one another. These forces depend upon i..

>Thus, if a solid is heated, its molecules vibrate more vigorously within the intermolecular space. Its internal energy increases and hence, its temperature increases. If the solids are heated further, at a certain stage their kinetic energy increases so much that many molecules can overc..

Rate of reaction basically means the speed at which a chemical reaction occurs. The speed of a reaction is determined by monitoring the concentrations of the reactants or products at intervals of time. The volume of the reaction vessel is kept constant and there is no addition to or remo..

Suppose an element A disintegrates into another element B. Let number of atoms of A when t = 0 is N 0 . A undergoes continuous disintegration into B and hence the number of atoms of A goes on decreasing. Let the number of atoms of A left undisintegrated in time t be N If dN atoms of A disin..

This method is used for reactions where more than one reactant species are involved. Initial rates of the reaction are determined by varying the concentration of only one reactant while keeping the concentrations of other reactants constant. Initial rate of reaction corresponds ..

For the reaction A Products, which follows first order kinetics, the rate of the reaction is proportional to the concentration of A raised to power 1. i.e., Integration of the differential equation gives In [A] = - kt + constant At t = 0, [A] = [A] o ln [A] o = const..

Rates of most chemical reactions increases with temperature because the rate constant 'k' increases with temperature. The temperature dependence of the rate constant is given by the Arrhenius equation, where..
