Rate Equation for F/F Reactions

Flashcards related to the concepts of mass transfer reactions and rate equations for gas-liquid systems.

Mass Transfer Resistance

The resistance encountered when reactants are brought together, affecting the rate of reaction.

Rate Equation

An expression that relates the rate of a chemical reaction to the concentration of the reactants.

Two-Film Theory

A theory describing mass transfer across interfaces, which assumes the presence of two thin films, one for each phase.

Henry's Law

A principle stating that the amount of gas dissolved in a liquid is proportional to its partial pressure above the liquid.

Liquid Film Enhancement Factor (E)

A parameter that describes how the presence of a reaction in the film enhances the uptake rate of a substance compared to straight mass transfer.

Hatta Modulus (MH)

A dimensionless number that indicates the relative rates of reaction and mass transfer; it helps to characterize reaction behavior in different regimes.

Instantaneous Reaction

A reaction that occurs so quickly that it can be considered to take place at the interface without a measurable delay.

Pseudo First-Order Reaction

A reaction where one reactant's concentration is much larger than the other, allowing it to remain approximately constant throughout the reaction.

Volume Fraction

A measure of the proportion of a particular component in a mixture relative to the total volume.

Concentration Ratio

The ratio of the concentrations of two reactants, which impacts the reaction rate.
