Which of the Following is Not a Standard Condition for Standard

Question

Which of the following is not a standard condition for standard free energy? A) 25 ⁰C B) 1 Atm. pressure C) Concentration of reactants = 1 molar D) Concentration of products = 1 molar E) pH = 7

Accepted Answer

Standard free energy conditions typically include 25°C, 1 atm pressure, and 1 M concentrations for both reactants and products. A pH of 7 is not a standard condition; standard conditions assume all species are at 1 M concentration, which corresponds to a pH of 0 for H⁺ ions.
