    Entropy (S) The second factor involved in determining whether or not a process is spontaneous is the change in randomness or entropy (AS). Entropy is represented by the symbol S. Again, experience can help us understand the relationship between entropy and spontaneous processes. If we look at the two drawings below, we can predict which picture represents the stack of marbles "before" and after they are bumped. We expect the stack of marbles (less random, lower entropy) to be the...

    6) When a spontaneou s, endothermic reaction occurs at constant temperature and pressure, the entropy change of the surroundings is: a) impossible to tell b) positive c) negative d) zero a) ΔG > 0 One finds that the equilibrium constant for a particular reaction increases with increasing temperature. Assuming that the standard reaction enthalpy and entropy are temperature independent, this means that: a) The standard reaction enthalpy is less than zero 8) b) The standard reaction entropy is greater than...
