Question

H2 reacts much faster with Cl2 than D2 because (A) rate of diffusion of H2 is greater than D2  (B)  H2 has lower energy of activation than D2  (C) Both (a) and (b) are correct . (D) None of the above is correct

Tardigrade Admin · Accepted Answer

H 2 reacts much faster with Cl 2 than D 2, because H 2 has lower energy of activation than D 2. This slowing of the reaction with the heavier isotope is called the deuterium isotope effect.

Q. $H_{2}$ reacts much faster with $C l_{2}$ than $D_{2}$ because

rate of diffusion of $H_{2}$ is greater than $D_{2}$

$H_{2}$ has lower energy of activation than $D_{2}$

Both (a) and (b) are correct .

None of the above is correct

$H_{2}$ reacts much faster with $C l_{2}$ than $D_{2}$ , because $H_{2}$ has lower energy of activation than $D_{2}$ . This slowing of the reaction with the heavier isotope is called the deuterium isotope effect.
