Consider the following reaction
` 2NO +2H_(2) rightarrow N_(2)+2H_(2)O `.
The given reaction follows the mechanism
( 1).`NO+NO harr N_(2)O_(2)`(Fast and reversible)
(II) `N_(2)O_(2)+H_(2)rightarrow N_(2)O+H_(2)O` (Slow)
(III) `N_(2)O_(2)+H_(2)rightarrow N_(2)+H_(2)O` (Fast)
If the concentration of both NO and `H_(2)` becomes thrice,then rate of reaction becomes ______ times.
