<span>1,3-cylohexadiene i synthesized starting from cyclohexane in following 4 steps.
1) Free Radical Substitution Rxn: Halogenation of cyclohexane in the presence of UV yield chlorocyclohexane.
2) Elimination Rxn: Dehydrohalogenation of chlorocyclohexane yields cyclohexene.
3) Halogenation of Cyclohexene (Electrophillic Addition Rxn) gives 1,2-dihalocyclohexane.
4) Elemination Rxn: When dibromocyclohexane is treated with KOH and heated it gives 1,3-cyclohexadiene as shown below,</span>

The order with respect to A is 2
The order with respect to B is 0.
The overall reaction order is 2.
<u>Explanation:</u>
The rate of chemical equation is represented by its rate equation. Here the rate equation of the given chemical reaction is
Here k represents the rate constant .
Order of the reaction with respect to its individual reactants is represented by the power of the the reactants in the rate equation.
Here the power of the reactant A is 0 and the power of reactant B is 2.
Hence the order with respect to A is 0 and order with respect to B is 2.
The overall order of the reaction is given by the sum of the powers of the reactants in the rate equation.
Hence the total order=2+0=2
