The interaction between the two atoms of H in H2 with the lower energy corresponds to a covalent bond between hydrogen's.
When the two atoms of H form a bond, they are overlapping the individual orbitals to form a new one. Every hydrogen has 1 electron which sits in a 1s orbital and then form one molecular orbital. The energy of H2 is lower than individual hydrogens because the electrostatic interaction between them.

Answer : The correct option for blank 1 is, Forward and Backward direction
.
The correct option for blank 2 is, Reach equilibrium
.
Explanation :
- Reversible reaction : It is a reaction in which two or more reactants react together to give products and these products react with other product to form reactants.
It occurs in both the directions at the same time, forward and backward direction.
- Irreversible reaction : It is a reaction in which reactants react together to give a product but it can not revert back into the reactants.
It occurs in forward direction only.
- Equilibrium reaction : It is a reaction in which the rate of forward reaction is equal to the rate of backward reaction.
- Completion reaction : It is a reaction in which the reactants react together to give products. when the reaction goes to completion theta means all the reactants are used up and you have only products in the reaction.
