The decompoistion of ammonia on platinum surface follows the change  `2NH_(3) rarr N_(2) + 3H_(2)`  (a) What does `(-d[NH_(3)])/(dt)` denote?  (b) What does `(d[N_(2)])/(dt)` and  `(d[H_(2)])/(dt)` denote?  ( c) If the decompoistion is zero order then what are the rates of Production of `N_(2)` and `H_(2)` if `k = 2.5 xx 10^(-4) M s^(-1)` ?  If the rates obeys `- (d[NH_(3)])/(d t) = (k_(1)[NH_(3)])/(1+k_(2)[NH_(3)])`, what will be the order for decompoistion of  `NH_(3)`, if (i) `[NH_(3)]` is every less and (ii) `[NH_(3)]` is very high? (`k_(1)` and `k_(2)` are constants)
