Molar Flux

Molar flux is used in chemistry and physics to describe the rate at which a certain number of moles of a substance passes through a specific surface area per unit of time.  It is often used to describe the flow of particles or molecules in processes like diffusion, gas exchange, or chemical reactions.  In some contexts, mole flux can be influenced by factors like concentration gradients (Fick's laws of diffusion), temperature, pressure, and other environmental conditions.

 

Molar Flux Formula
\( J \;=\;  n \;/\; A \; t \)     (Molar Flux) \( n \;=\;  J \; A \; t \) \( A \;=\;  n \;/\; J \; t \) \( t \;=\;  n \;/\; J \; A \)
Symbol	English	Metric
\( J \) = Molar Flux	-	\(mol\;/\;m^2-s\)
\( n \) = Number of Moles	-	\(mol\)
\( A \) = Surface Area Through Which the Substance is Moving	-	\(m^2\)
\( t \) = Time Change	-	\(s\)
