Question
The following processes occur at constant temperature. Predict the sign of Delta S for each of the following processes. I. Butter in a butter dish melts because it's a hot day in Marquette. II. Water droplets condense on the surface of a drinking glass containing a cold beverage. a. I: Delta S = positive; II: Delta S = positive b. I: Delta S = negative; II: Delta S = negative c. I: Delta S = negative; II: Delta S = positive d. I: Delta S = positive; II: Delta S = negative If. Calculate Delta G degree at 27.5 degree for the following equilibrium bused on the equilibrium concentrations below. Units: kJ/mol 3 A + 1 B = 1 C Data [A] = 0.116 M [B] = 0.126 M [C] = 0.132 M a. -22.8 b. -16.2 7 c. -1.49 d. -9.13Explanation / Answer
Ans 7 option d. I. delta S = postive ; II. delta S = negative
delta S represents the change in entropy of the system
Entropy is the degree of randomness or disorderness of the system
In I butter changes from solid to liquid state so entropy increases in the product side hence delta S is positive.
in II water droplets condense, that means liquid to solid transformation takes place, and entropy decreases in product side, hence delta S is negative
