Part B The desorption of a single molecular layer of n-butane from a single crystal of aluminum oxide was found to be first order with a rate constant of 0.128 /s at 150 K. If the surface is initially completely covered with n-butane at 150 K, how long will it take for 25% of the molecules to desorb? Express your answer using two significant figures.

Acids and Baser Calculating the \( \mathrm{pH} \) at equivalence of a titration A chemist titrates \( 60.0 \mathrm{~mL} \) of a \( 0.6732 \mathrm{M} \) potassium hydroxide \( (\mathrm{KOH}) \) solution with \( 0.8187 \mathrm{MHCl} \) solution at \( 25^{\circ} \mathrm{C} \). Calculate the \( \mathrm{pH} \) at equivalence. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of \( \mathrm{HCl} \) solution added.

A free particle of momentum p is represented by a plane wave. A measuring apparatus determines that the particle lies inside a region of length L. Assume the in that region the wavefunction of the particle is still represented by a plane wave. The resulting interaction with the particle is assumed to leave the wavefunction unchanged for a length L, but to reduce to zero outside this region. What are the average momentum and the average kinetic energy of the particle after the measurement has been made?
