Five questions from the pack.

0 of 5 answered

Q1Which of the following is a state function?

B. Entropy depends only on the state. Heat and work depend on the path, and the path itself is not a property of a state. The other choices fail because each describes a quantity tied to how the change happened.

Q2During the boiling of water at 1 atm, the heat supplied

B. At the plateau, energy overcomes intermolecular attractions. T and average KE stay constant, and vapor pressure equals the external pressure.

Q3For a spontaneous process, ΔS(system) = -40 J/K. This is possible if

B. The second law needs ΔS(universe) > 0. A system can lose entropy when the surroundings gain more. In an isolated system ΔS(sys) itself must be positive.

Q4A reaction has k = 4.0 x 10^-3 s^-1. The overall order is

B. A unit of s^-1 is the signature of first order, because rate (M/s) = k[A] requires k in s^-1. Zero order would need M/s, second order M^-1 s^-1, and third order M^-2 s^-1.

Q5Which conditions favor the thermodynamic product?

B. Equilibration lets material funnel to the most stable product. Low T, short time, and irreversibility lock in the kinetic product.

Those are real questions from the pack, word for word.
