Peer reviewedHaynes, Henry W., Jr. – Chemical Engineering Education, 1986
Current chemical engineering textbooks teach that the driving force for diffusive mass transport in ideal solutions is the gradient in mole fraction. This is only true for ideal solution liquids. Therefore, it is shown that the appropriate driving force for use with ideal gases is the gradient in partial pressure. (JN)

Peer reviewedSeeman, Jeffrey I. – Journal of Chemical Education, 1986
Discusses: (1) the Curtin-Hammett (C-H) equation; (2) a direct relationship between product ratio and conformer distribution; (3) the Winstein-Holness (W-H) equation; (4) a combined kinetic treatment using a C-H/W-H utility; and (5) extensions of the C-H/W-H concepts. (JN)
