2 A + 2 B + C → D + 3E(a)
in reactant the reaction order for [A] = 2, [B]= 2, [C]=1
and for product part [D]= 1, [E]= 3
In a chemical reaction, the relation between its rate and the concentration of the elements is called as order of the reaction.
Order of reaction shows reactant entities whose concentration directly affects the rate of reaction.
The number of order of reaction can be obtained by the total of exponents of concentration in the expression of the rate of reaction.
A reaction is called as first order if the rate of reaction is depend on the concentration of the reactants.
If rate = k[a][b]3, then order in a is 1 while the order in b is 3.
