Question

A photochemical reaction\ $\mathrm{A}_{2}+\mathrm{B}_{2} ightarrow 2 \mathrm{AB}$ occurs by the following mechanism:\ $\mathrm{A}_{2} \xrightarrow{\mathrm{~h} 
u} \mathrm{~A}+\mathrm{A} \ldots$. (slow)\ $A+B{ }_{2} ightarrow A B+B \ldots$. (fast)\ $A+B ightarrow \quad A B \ldots$ (fast)\ Its order would be\
