Irregular trend in the standard reduction potential value of first row transition elements is due to

Question

Irregular trend in the standard reduction potential value of first row transition elements is due to (A) regular variation of first and second ionisation enthalpies (B) irregular variation of sublimation enthalpies (C) regular variation of sublimation enthalpies (D) increase in the number of unpaired electrons

Tardigrade Admin · Accepted Answer

Since, the enthalpies of sublimation of first row transition elements varies irregularly, their standard reduction potential also exhibit a irregular trend.

Q. Irregular trend in the standard reduction potential value of first row transition elements is due to

regular variation of first and second ionisation enthalpies

irregular variation of sublimation enthalpies

regular variation of sublimation enthalpies

increase in the number of unpaired electrons

Since, the enthalpies of sublimation of first row transition elements varies irregularly, their standard reduction potential also exhibit a irregular trend.
