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.
