(a) For a reaction, the rate law is : Rate `=k=[A][B]^(1//2)`. Can this reaction be an elementary reaction ?
(b) The possible mechanism for the reaction : `2" H"_(2)+2" NO"to N_(2)+2" H"_(2)O` is
(i) `2" NO" iff "N"_(2)"O"_(2)` (ii) `N_(2)O_(2)+H_(2)to N_(2)O+H_(2)O" (slow)"` (iii) `N_(2)O+H_(2)to N_(2)+H_(2)O" (fast)"`
What is (i) the rate law for the reaction (ii) order of the reaction.
