Question

A process which is unfavorable with respect to enthalpy, but favorable with respect to entrophy

a)could occur at high temperatures, but not at lower temperatures
b)could not occur regardless of temperature
c)could occur at any temperature
d)could occur at low temperatures, but not at higher temperatures
e) none of the above

Answer 1

delta G = delta H -T*delta S.
delta G must be negative for the reaction to occur spontaneously.
delta H is unfavorable; therefore, it probably is +.
delta S is favorable; therefore, it is positive.
Now use that information to answer the question.
