In the process of dissolving salt in water, the entropy increases. This means that the sign of as is (positive negative), and that the randomness of the system (increases, decreases, stays same).

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...

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...

Is the dissolution process studied today, NaNo, (s) → Na+ (aq) + NO3-(aq) spontaneous or nonspontaneous? How can you tell? What is the sign of ΔΟ? 1. Using the class's mean value for ΔH and the Gibbs-Helmholtz equation, estimate the value for as for the dissolution process. (See Calculations section.) 2. Based on your observation about the spontaneity o the...
