Which of the following statement is incorrect?

The entropy of the universe increases and tends towards the maximum value in irreversible process.

All the natural spontaneous processes are irreversible in nature

For the isothermal expansion of an ideal gas, `DeltaH and DeltaE` are not equal

The heat of formation of an element in the standard state is zero

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 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.
