Question
E^n cell is the standard cell potential. The entropy of a pure perfect crystal is zero at -27315 degree C.. A spontaneous reaction is one that must have a negative value of Delta H. In a galvanic cell, reduction occurs at the anode Delta G is positive for a spontaneous reaction An oxidizing agent is reduced during a redox reaction. Entropy is related to the way in which the energy of a system is distributed among the available micro-states energy levels. A chemical equation is a shorthand way of representing a chemical reaction Corrosion of metals is an oxidation reduction process A zero means the system is at equilibrium. Choose the one alternative that best completes the statement or answers the question. Choose the Incorrect statement A) a cell diagram is a symbolic way to show cell components B) Half cells are separated by a angle vertical line C) An anode is where oxidation occurs. D) The anode is on the left in a cell diagram E) A cathode Is where reduction occursExplanation / Answer
Question 1.
Correct since the "°" stands for "Standard states" and Ecell stands for the cell potential. TRUE
Question 2.
Correct, since this is the definition of the absolute ZERO, TRUE
Question 3.
False, it must have a NEGATIVE value in dG, This is FALSE
Question 4.
reductino will occur at the CATHODE, since thats the place cations go to gain electrons (typically). This is FALSE
Question 5.
dG is negative for a spontaneous, therefore FALSE
Question 6.
Correct, since it aids in oxidation, therefore must reduce
Question 7.
True, the higher chaos, the more entropy
Question 8.
True, it helps us understand what is going on
Question 9.
TRUE, since one species is losing elctrons, the other gaining
Question 10.
True, if dG phase 1 = dG phase 2, this is in equilbirium
