Answer : The correct option is, (1) a chemical change, because a compound is formed

Explanation :

Physical change : It is a change in which no new compound or substance is formed only changes in the phase.

Chemical change : It is a change in which a new compound or substance is formed and also some energy releases. There is no changes occurs in the phase.

When a molecule of H_2 and a molecule of I_2 collide with proper orientation and sufficient energy then the chemical changes occurs due to the formation of the new compound.

Hence, the correct option is, (1) a chemical change, because a compound is formed
