5 of 15 A reaction is non-spontaneous. What can you conclude about the reverse reaction? O It is spontaneous. It must be exothermic O It must have an increase in entropy O It is in equilibrium. 6 of 15 Based on the AG calculation, a student determined that a synthesis reaction should be spontaneous. When the student tries out the reaction, however, nothing happens. Which explanation is most plausible? O the student probably made a mistake in the calculation O...

Name 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...
