A certain endothermic reaction: `Ararr` Product, `DeltaH=+ve` proceeds in a sequence of three elementary steps with the rate constants `K_(1), K_(2)` and `K_(3)` and each one having energy of activation `E_(a), E_(2)` and `E_(3)` respectively at `25^(@)C`. The observed rate constant for the reaction is equal to `K_(3) sqrt(K_(1)/K_(2)). A_(1), A_(2)` and `A_(3)` are Arrhenius parameters respectively. The observed Arrhenius parameter for the reaction is:A. (a) `(2A_(1)-A_(2)+2A_(3))/(2)`B. (b) `sqrt(A_(1)/A_(2)).A_(3)`C. (c ) `A_(1)A_(2)A_(3)`D. (d) `(A_(1).A_(3))/(A_(2))`
