✦ Synopsis

T = tortuosity factor (taken as 2); and tj = effectiveness factor; cp =Thiele modulus. Correspondence* Intrinsic reactivity of carbons to oxygen Jamuluddin et al.' are correct to point out the error in the characteristic dimension used to determine the intrinsic reactivity of various carbons2s3. The consequences of the error do not significantly affect the conclusions about the relative reactivities of various carbons, nor the very large differences (by orders of magnitude) in the reactivities of different types of carbons at equal temperatures and oxygen concentrations3.

Nonetheless the error can have an important consequence for engineering purposes. Should it be necessary to use the intrinsic reactivity data of Figure 1 of reference 3 to calculate burning rates, the error will be cancelled, and the correct rate calculated, if the dimension y/2 is used for this purpose, in this circumstance alone.
