(a) Heating at constant volume followed by cooling at constant pressure.

(b) Isothermal compression.

(c) Adiabatic compression followed by cooling at constant volume.

【已刪除】2. An ideal gas with constant heat capacities, C_v and C_p, undergoing a reversible adiabatic process from State 1 of T₁ and P₁ to State 2 of T₂ and P₂. Prove that

whereγ = C_p/C_v. (20 points)

【已刪除】3. The decomposition of urea in 0.1 M HC1 occurs according to the reaction

The first-order rate constant for this reaction was measured as a function of temperature, with the following results:

Calculate the activation energy and derive an expression of the rate constant as function of temperature. (30 points)

【已刪除】(a) Calculate the energies of the two states of lowest energy for an electron in a one-dimensional box of length 2.0

. (10 points)

【已刪除】(b) What is the probability that the electron is within 0.5

of the center of the box in the lowest energy state? (10 points)

[Hint] The probability of finding the electron in a finite volume of space is obtained by integration over the volume:

and the wavefunction for a particle in a box is:
