1. (Total 10 points) Indicate "O" for correct statements and "X" for incorrect statements. (1) The standard reduction potential is a ratio scale, like Kelvin. [Hint: Celsius and Fahrenheit are interval scales, but Kelvin is a ratio scale.] ( ) (2) Entropy could be considered to be measured on a ratio scale, in accordance with the third law of thermodynamics. ( ) (3) Given that Ecell˚ for A + B → C + D is e, Ecell˚ for 2A + 2B → 2C + 2D is also e, because Ecell˚ is an extensive property, like ΔGo. ( ) (4) The steady state in chemical kinetics is an equilibrium state. ( ) (5) The pH value is equal to pKa when [HA] is equal to [A-], especially for weak acids. ( ) (6) All spontaneous processes produce an increase in the entropy of the system. ( ) (7) During phase transitions, the change in enthalpy equals the product of the change in entropy and the absolute temperature. ( ) (8) The equilibrium is reached at the point, where the slope of the Gibbs free energy versus extent of reaction graph is zero. ( ) (9) Fractional distillation can be explained by Henry’s law. ( ) (10) Aniline is more basic than cyclohexylamine due to the electron delocalization. ( )
