A scientist is studying the kinetic isotope effect in a reaction involving deuterium. They find that the rate constant for the reaction with heavy water () is significantly smaller than that with normal water (). This difference is primarily attributed to the:
Higher viscosity of compared to .
Difference in zero-point vibrational energies of the O-H and O-D bonds.
Greater dielectric constant of compared to .
Difference in the nuclear spins of deuterium and hydrogen.
