For the reaction : 2" NH"_(3)(g)overset("Pt")to"N"_(2)(g)+3" H"_(2)(g), Rate = k (i) Write the order andmolecularity of this reaction. (ii) Write the units of k.

Answer»

SOLUTION :(i) Rate = k shows that the rate of reaction is independent of the concentrations of the reactants. Hence, it is a reaction of zero order. As two molecules of the REACTANT are persent in the reaction, molecularity is two.
(ii) UNITS of k will be same as that of the rate of reaction viz. `"mol L"^(-1)s^(-1)`.
