2 mildly simple questions with multiple choice
« on: November 13, 2012, 10:02:17 PM »
The work involved in moving exactly 1mol of electrons through a potential difference of exactly 1 V is...

A. 1 J
B. 1 kJ
C. 96.5 J
D. 6.02 kJ
E. 96.5 kJ

Which statement does NOT describe a "dead" battery with a voltage of 0?

A) The Free-energy change for the reaction is now 0
B) All the reactions have bene converted into products
C) The products and reactants now are in equilibrium
D) Q = K
E) cell potential = 0
