Which of the following statement is incorrect ?

The stability constant of `[Co(NH_(3))_(6)]^(3+)` is greater than that of `[Co(NH_(3))_(6)]^(2+)`

The cyano complexes are more stable than those formed by halide ions

The stability of halide complexes follows the order `I^(-)lt"Por"^(-)ltCl^(-)ltF^(-)`

The stability constant of `[Cu(NH_(3))_(4)]^(2+)` is greater than that of `[Cu(en)_(2)]^(2+)`

The rate law for any reaction cannot be determined experimentally

Complex reactions have fractional order

Bimolecular reactions involve simultaneous collision between two species

Molecularity is only applicable for elementary reaction.

`La(OH)_3` is less basic than `Lu(OH)_3`

In lanthanide series ionic radius of decreases from `La^(3+) " to" Lu^(3+)` ion

La is actually an element of transition series rather than lanthanides

Atomic radius of Zr and Hf are same because of lanthanide contraction
