Answers
Answer:
Given the electrochemical reaction shown, what is the standard free energy change Delta G degree if E degree = +1.61 V? Mg/Mg^2+(aq)//Zn^2+(aq)/Zn E degree = +1.61 V a. -311 kJ/mol b. +311 kJ/mol c. -155 kJ/mol d. +155 kJ/mol e. none of the above The oxidation of hydrogen by oxygen is one of the most-used reactions in fuel-cell technology. The overall reaction, which is given below, has a Delta G degree value of -474 kJ/mol. What is the standard cell potential for this fuel cell? 2H_2(g) + O_2(g) rightarrow 2H_2O(l) Delta G degree = -474 kJ/mol a. 2.46 V b. 4.91 V c. 1.23 V d. 2.46 V e. 1.50 V What is Delta G degree for the following balanced reaction, if E degree = +2.431 V? Al(s) + Fe^3+(aq) rightarrow aI^3+(aq) + Fe(s) a. -704 kJ/mol b. +704 kJ/mol c. -235 kJ/mol d. -469 kJ/mol
