Question:

If a reaction has a low, unfavorable entropy, but a high favorable enthalpy then the reaction will occur at what kind of temperatures? High (temperatures above 0 Kelvin) ? Low (temperatures below 0 Kelvin)? or All?

Joanna R.
Answer:

The reaction will occur at all temperatures because the enthalpy of the reaction is high and favorable ( extremely exothermic) and the entropy of the reaction is low and unfavorable. Based on the thermodynamics equation: Delta G = Delta H - (Delta S)(Temperature), the product of Delta S and Temperature would be small if Delta S is small. If the product of Delta S and Temperature is small, then the effect it will have on the equation is small. Since Delta H is high and favorable and the effect of the product of Delta S and Temperature is small, then the overall reaction is favorable and will occur.

Question:

If Compound A has a higher energy level than Compound B, then Compound B is more stable or less stable than Compound A?

Joanna R.
Answer:

Compound B is more stable than Compound A. The reasoning for this answer is level of energy and stability are inversely proportional. This means if energy is high, stability is low, and vice versa.
