1.	Assertion . When two hydrogen atoms approach each other to form a cavalent bond , nearly435.8 KJ mol^(-1) of energy is released . Reason .When two atoms approach eachother to form a covalent bond between them, potential energy of the system is released .
Answer» If both ASSERTION and reason are CORRECT, and reason is the correct explanation of the assertion. If both assertion and reason are correct , but reason is not the correct explanation of the assertion. If assertion is correct, but reason is incorrect . If both assertion and reason are incorrect. Solution :Correct R . When two atoms approach each other to form a covalent BOND between them , potential ENERGY of the system FIRST decreases and then increases .
