In hypothetical reaction, `A_(2)+B_(2)rarr2AB`, follows the follows the mechnism as given below : `{:(A_(2)hArrA+A,("fast reaction")),(A+B_(2)rarrAB+B,("slow reaction")),(A+BrarrAB,("fast reaction")):}` Give the rate law and order of reaction |

Answer» Slowest step is rate eleminated. `K_(c)=([A][A])/([A_(2)])=([A]^(2))/([A_(2)])` `[A]=K_(c)^(1//2)[A_(2)]^(1//2)` From eq. (i), Rate `=kK_(c)^(1//2)[A_(2)]^(1//2)[B_(2)]` `=K[A_(2)]^(1//2)=[B_(2)],[K=*K_(c)^(1//2)]` Order =1+1/2=3/2 |
