Question

The percentage of para hydrogen in ordinary hydrogen increases when:(answer must be realted to pressure or temperature)​

Answer 1

Answer:

Molecular hydrogen occurs in two isomeric forms, one with its two proton spins aligned parallel (orthohydrogen), the other with its two proton spins aligned antiparallel (parahydrogen). At room temperature and thermal equilibrium, hydrogen consists of approximately 75% orthohydrogen and 25% parahydrogen. So ratio of ortho and para hydrogen in ordinary hydrogen is 3:1.
