If the rate-determining step of a reaction is This is an image of a chemical equation. A + 2B, reaction arrow, C. , the reaction
rate is represented by (assume it is third order overall and the concentration of B is a bigger rate determinant than concentration of A): a.k[A] 2[B]
b.k[A][B]2
c.k[B]2
d.k[A][B]2[C]
The reaction rate of a chemical reaction is determined by the slow step in the reaction mechanism.
The rate ii given by the product of the species of the determining step, each raised to its coeeficient in the chemical reaction that represents this step.
So, given that the determining step is represented by A + 2B→C, the reaction rate is r = k[A]*[B]^2.
This mechanism is verified becasue the total order is the summ of the coefficientes : 1 + 2 = 3 and the exponent 2 makes B is a bigger rate determinant than A.
In many cases, elements that belong to the same group (vertical column) on the periodic table form ions with the same charge because they have the same number of valence electrons.
