Rate laws of reactions

Post by Dhamnekar Winod »

Iron powder rusts at a much faster rate than an iron nail.

Is this statement true?
If yes, what is your explanation?
If no, what is your explanation?
Any science consists of the following process. 1) See 2)Hear 3)Smell,if needed 4)Taste, if needed 5)Think 6)Understand 7)Inference 8)Take decision [Believe or disbelieve, useful or useless, true or false, cause or effect, any other criteria]

Author of my chemistry notes explains as follows:

Rusting is a heterogeneous process. Iron powder has a greater surface area than a iron nail of a same mass. Therefore , agents responsible for rusting may attack more iron sites at the same time on the iron powder sample.
