What role does entropy play in chemical reactions?
A) The entropy determines how much product will actually be produced.
B) The entropy change determines whether the reaction will be exothermic or endothermic.
C) The entropy change determines whether the reaction will occur spontaneously or not.
D) The entropy change determines whether or not the chemical reaction is favorable.
Question 2
Bond energies increase in going from C-N (lowest) to C-O to C-F (highest). Explain this trend based upon the atomic sizes of these atoms as deduced from their positions in the periodic table.
A) In going from nitrogen to oxygen to fluorine the atoms get larger. This means a greater nuclear charge, which translates into stronger chemical bonds.
B) In going from nitrogen to oxygen to fluorine the atoms get smaller. This means a greater nuclear charge, which translates into stronger chemical bonds.
C) In going from nitrogen to oxygen to fluorine the atoms get larger. This means that the bonding atoms are farther apart, which translates into a greater bond energy.
D) In going from nitrogen to oxygen to fluorine the atoms get smaller. This means that the bonding atoms are closer together, which translates into a greater bond energy.
