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…
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…
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…
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…
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…
Integrated Rate Expression of Zero Order Reaction: Consider the general reaction: A —————-> products If it is a reaction of zero order then, Rate = -d / dt = k…
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…
Consider the two different initial concentrations and finding their half lives, the order of reaction (n) can be calculated as follows: Taking log on both sides we will get: log…
Amount of the substance left after one half life = A0 / 2 Amount of the substance left after two half lives = A0 / 22 Amount of the substance…
Experimental methods for determination of rate constant are discussed below: 1. Concentration change method: In this method the concentration of one of the reactants or products is measured at different…
