1.	Some times a reacant undergoes chemical/radioactive changes followingtwo or more different pathsto yield twoor more different producesrespectively. Such reactions are called parallel path reactions. If K_(1) and K_(2) are rate constans for the reaction of A follwing two parallel paths, then Then K_(av) = K_(1) + K_(2) If average life of A for p is T_(1) and for Q is T_(2) then:
Answer» `T_(AV) = T_(1) + T_(2)` `T_(av) = (T_(1)T_(2))/(T_(1) + T_(2))` `T_(av) = (T_(1) + T_(2))/(T_(1)T_(2))` `T_(av) = K_(1) T_(1) + K_(2) T_(2)` SOLUTION :`K_(av) = (1)/(T_(av))`
