Question

Why is ortho hydrogen much more stable than para hydrogen at high temperature?​

Answer 1

Answer:

- In the structure of ortho hydrogen, the proton nuclear spins are aligned parallel to each other. While in para hydrogen, the proton nuclear spins are aligned antiparallel to each other. ... - Now, due to antiparallel spin arrangement, para hydrogen has less energy and thus, they are more stable than ortho hydrogen.
