Question

True or False. Provide explanations for your answers. Make sure you define appropriate terms.

a. If G° for a reaction is greater than zero, the process will not occur spontaneously.

b. The compression factor, Z, of most gases is less than 1 at very low temperatures.

c. Negative deviations from Raoult’s Law occur when solute-solvent interactions are very strong.

d. Solutions of dissolved gases in water typically follow Raoult’s Law.

e. The second virial coefficient is usually negative.

f. The internal pressure of a real gas is equal to zero.

g. The rate constant for a bimolecular chemical reaction does not depend on collision frequency..

h. If S for a process is less than zero, it does not occur spontaneously

a. If G° for a reaction is greater than zero, the process will not occur spontaneously. TRUE, since there is no free energy left

b. The compression factor, Z, of most gases is less than 1 at very low temperatures. True, since that is the common trend in Tr

c. Negative deviations from Raoult’s Law occur when solute-solvent interactions are very strong. TRUE, since they will interact between each other

d. Solutions of dissolved gases in water typically follow Raoult’s Law. True, since they are dilute

e. The second virial coefficient is usually negative. True, but this is a broad generalization

f. The internal pressure of a real gas is equal to zero. False, oninteral pressure is 0

g. The rate constant for a bimolecular chemical reaction does not depend on collision frequency.. False, they must follow universal rules

h. If S for a process is less than zero, it does not occur spontaneously. False, it must be the one of the universe
