Half Life Period is defined as the time taken for half of the reaction to be completed i.e. the time in which the concentration of a reactant is reduced to half of its original value is called Half Life Period of the reaction. General expression for ...

Integrated Rate Expression of Zero Order Reaction: Consider the general reaction: A ----------------> products If it is a reaction of zero order then, Rate = -d [A] / dt = k [A] 0 = k d [A] = - k dt Integrating both sides, we will get: [A] = - kt + ...

Difference between photochemical reactions and thermochemical reactions are discussed below: THERMOCHEMICAL REACTIONS PHOTOCHEMICAL REACTIONS These reactions involve absorption or evolution of heat. These reactions involve absorption of light. They can take place even in absence of light i.e. dark. The presence of light ...

The main difference between the order of a reaction and molecularity of a reaction are given below: ORDER OF A REACTION MOLECULARITY OF A REACTION It is sum of the concentration terms on which the rate of reaction actually depends or it is the ...

A series of step reactions or elementary processes proposed to account for the overall reaction is called the mechanism of the reaction. The writing of step reactions is usually based upon the experimental evidence. For example: The detection of the presence of some short lived intermediates etc. ...

In case of chemical reactions i.e. reactions involving a number of atoms, ions, molecules of the reactants in the balanced equation, the chances for all the atoms, ions or molecules of the reactants to come together and collide are very rare. Hence in such cases, ...

According to the collision theory in order that a reaction may take place, the molecules must come close together and collide with one another. Hence, The number of atoms, ions or molecules that must collide with one another simultaneously so as to result into a chemical reaction ...

Difference between rate of reaction and reaction rate constant are as follows: RATE OF REACTION REACTION RATE CONSTANT Rate of reaction is the change in concentration of a reactant or product per unit time. It is a constant of proportionality in the rate law equation ...
