$$H2$$ reacts faster with $$Cl2$$ at 13 times faster rate than $$D2$$ because:

A

$$H2$$ has high activation energy

B

In $$H2$$, $$H-H$$ bond energy is higher than $$D-D$$ bond energy in $$D2$$

C

$$H2$$ has low activation energy because $$H-H$$ bond energy is lower than $$D-D$$ bond energy

D

In $$H2$$ there is no neutron therefore it reacts faster
