Question

For a reaction in which all reactants and products are liquids, which one of the following equations is most applicable ?

• A. $\Delta H < \Delta E$
• B. $\Delta H = \Delta S$
• C. $\Delta H = \Delta E$
• D. $\Delta H = \Delta G$

Answer 1

Answer: (C)

$\Delta H = \Delta E$

Answer 2

As all reactant and product are liquid $\Delta n_{(g)} = 0$ $\Delta H = \Delta E - \Delta nRT$ $\Delta H = \Delta E \, \, \, (\because \, \Delta n = 0)$
