Which of the following is incorrect for H2, D2 and T2?
Their physical properties differ considerably due to large difference of their masses.
Chemical properties are almost same due to same electronic configurations 1s1 of 11H, 12H and 13H.
13H disintegrates producing 23H high energy β-particles.
Their rates of reactions differ due to different bond enthalpies.
H 13 → β -10 (of low energy) +He 23
