Question

H2 gives 2H

entropy increase or decrese?

Answer 1

 H2 gas give 2*H gas atoms as number of gaseous atoms increases randomness increases ...Entropy is a measure of randomness, more are the disorderly arranged particles in a system, more is the randomness and more is the entropy. So entropy increases when H2 breaks into 2 H atoms. 

Answer 2

Answer:

H2 gives 2H

Explanation:

In this process,one molecule of hydrogen gas dissociated into two gaseous atoms i.e.,the number of gaseous particles increase leading to a more disordered state . Reason is also correct as breaking of bond requires energy. However,the reason doesn't explain the Assertion being made .
