Pick out the wrong statement.
Visible radiation provides the necessary activation energy in photochemical reactions.
The order and molecularity of a complex reaction may not be the same.
For a second order reaction, the slope of the graph/plot between rate and (concentration) is equal to the rate constant (k).
Molecularity of the reaction is always a whole number greater than zero.

Molecularity is only defined for an elemental reaction, i.e., a reaction proceeding in a single step. A complex reaction cannot have a molecularity as a whole. Only each step of a complex reaction has a molecularity.

No, the slope is not linear in the second order. So I think the correct answer is C.

Because molecularity is not defined for complex reactions.
