← ScienceWhich outcome results from deuterium isotopes replacing hydrogen atoms?
A)Reduced reaction kinetics catalytic converters✓
B)Increased energy production fusion reactor
C)Enhanced drug efficacy pharmaceutical products
D)Decreased chain reaction nuclear reactor
💡 Explanation
Replacing protium with deuterium results in a kinetic isotope effect causing slower reaction rates because C–D bonds are stronger, requiring more energy to break, compared to C-H bonds; therefore, reaction kinetics are reduced, rather than altering energy, mechanisms, or causing chain reactions
