Before asking an educational question you must do some homework. Read textbooks.
KIE stands for Kinetic Isotope Effect, and it's a dimensionless value used in catalysis chemistry to study the effect of isotopic substitutions on reaction rates. The KIE is often expressed as the ratio of the rate constants for a reaction with different isotopes of the same element, typically hydrogen (H) or deuterium (D).
For example, if you have a reaction involving the breaking of a C-H bond and you compare the reaction rate when hydrogen (H) is present with the rate when deuterium (D) is present, you can calculate a KIE to understand how the isotope substitution affects the reaction kinetics. The equation for KIE is usually expressed as k_H/k_D, where k_H is the rate constant with hydrogen, and k_D is the rate constant with deuterium.
A KIE value greater than 1 implies that the reaction is faster with hydrogen, while a KIE value less than 1 indicates the reaction is faster with deuterium. KIEs are useful in studying reaction mechanisms, identifying the rate-determining step, and providing insights into bond-breaking and bond-forming processes in catalysis chemistry.
Manpreet Singh Sandhu Your answer is correct, but reading of textbooks remains necessary. In addition, "KIE's PH/PD value" means the KIE if H2O is replaced with D2O.
