Question

At 1 bar and 298 k, standard molar enthalpy of formation of which substance is zero. (1) h(g) (2) h+ (aq) (3) h+ (g) (4) all correct

Answer 1

Answer ⇒ No Options are Correct among the Given options.

Explanation ⇒ Molar Enthalpy of only naturally State of the substance is taken as zero. But in all the options, there is not an single substance which is the natural state.

For example, Natural state of the Hydrogen is H₂.

It does not found in nature as H, or H⁺ etc, but it found as Di-hydrogen.

Hence, No options are correct.

Hope it helps.
