1. In the rusting of iron delta H= -376.44 kcal/mol K; delta S = -0.1708 dcal/mol K and delta G = 329.8 dcal/mol. Is it driven by enthalpy or entropy? Please explain.
2. Entropy is a measure of the amount of "disorder" in a system. Increase in disorder means high entropy,while increase in order means low entropy. If you were given a colored solution and any other resource of your choice and you are told to demonstrate entropy and disorder in a classroom full of kids (which demonstrates entropy and enthalpy) how would you do this?
1. The best way to analyze this problem is to look at the thermodynamic equation:
Delta(G) = Delta(H) - T*Delta(S)
In the problem Delta(H) is negative, Delta(S) is negative and Delta(G) is positive. Delta(G) is the called the Gibbs Free Energy and this is what is used to ...
This response discusses the concept of enthalpy and entropy, and demonstrates how each of these terms are used in different scenarios.
