Which of the following correctly describes how rate laws are determined? Rate laws can be determined from the coefficients of balanced equations. The rate law for an elementary step can only be determined from unimolecular reactions. The rate law for the overall reaction is always determined by the rate law of the fastest step. Rate laws are determined through experimentation.

To answer this question, we must go through a process of elimination.

A. This is only true for elementary reactions; It does not apply to all.
B. This is not only applicable to unimolecular but to bimolecular and so on and so forth.
C. The contrary is true. The slowest reaction would be the basis because it is the rate-limiting step.
D. This is true.

The answer is D.
