Which thermodynamic parameter is common for both reaction given.
(I) $H_{2 (g)} \to 2 H_{(g)}^{+}$
(II) $H_{2 (g)} \to 2 H_{(g)}^{-}$

Question

Which thermodynamic parameter is common for both reaction given. (I) H 2 ( g ) ​ → 2 H ( g ) + ​ (II) H 2 ( g ) ​ → 2 H ( g ) − ​

TestHub · Accepted Answer

Given reactions: (I) H 2 ​ ( g ) → 2 H + ( g ) represents the removal of electrons from hydrogen atoms. (II) H 2 ​ ( g ) → 2 H − ( g ) represents the addition of electrons to hydrogen atoms. Both reactions require breaking the H–H bond present in the H₂ molecule before forming ions. Therefore, the common thermodynamic parameter involved in both processes is bond energy of H₂. Correct Answer: (D) Bond Energy
