Electronegativity is your answer.
Explanation:
The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant.
The overall order of reaction is the sum of the individual orders of reaction with respect to the reactants.
Rate = k [A]²[B]¹
In the rate law above, the rate is second order with respect to A and first order with respect to B. The overall order of reaction is a third order reaaction given as; 2+ 1 = 3
Valence.
The electrons in the outer shell of an atom are called valence electrons.
Valence electrons determine whether the an element is ready form compounds. These electrons can be gained, lost, or shared in the formation of compounds.
