What is the connection between entropy and a spontaneous reaction?
a) A reaction is less likely to be spontaneous if it increases the entropy of a system.
b) A reaction is more likely to be spontaneous if it increases the entropy of a system.
c) A spontaneous reaction always decreases the entropy of a system.
d) A spontaneous reaction does not affect the entropy of a system.

For a process to be spontaneous: a) b) the entropy of universe increases and Gibbs energy of the system decreases. the entropy of system decreases and Gibbs energy of the universe increases. the entropy of system increases and Gibbs energy of the universe decreases the entropy of universe decreases and Gibbs energy of the system increases. c) d)
why are the other options wrong?
For a process to be spontaneous: the entropy of universe increases and Gibbs energy of the system decreases. a) the entropy of system decreases and Gibbs energy of the b) universe increases. the entropy of system increases and Gibbs energy of the universe decreases. c) of universe decreases and Gibbs energy of the d) the entropy increases system
A reaction which is exothermic and has an overall increase in entropy is: a. spontaneous only at high T b. spontaneous only at low T c. always spontaneous d. spontaneous in the reverse direction
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...
