You are the teacher and need to create a word problem to go along with the image below. Make sure that your problem asks about distance and displacement and is creative. Finally, you must include a thorough answer key for your own problem, making sure to show all work and include the correct units.
A reaction 𝐴 + 𝐵 → 𝑃 has been studied with the half-time method to determine a total order of a reaction and the rate constant. The experimental measurements determined the following characteristic equation:
log6𝑡!/#7 = 0.290618 + 0.500 ∗ log(𝐴$)
(a) Find the total order, and the rate constant of the reaction.
(b) State if and when one has to be cautious using the half-time method to determine the order or the rate constant of a reaction.
(c) State if the method can be used to determine orders of reaction with respect to individual reactants. If yes, briefly describe what needs to be done to determine these orders.
The quantum-mechanical solutions show that the amplitude of the oscillating particle goes from −∞ to +∞. However, the probability of finding a particle at the large distances from the equilibrium is extremely small.
Therefore, one could use an approximate form of a harmonic oscillator wavefunction shown below:
𝜓(𝑥)=(𝐿 −𝑥 )
where the amplitude of an oscillation, x, is limited to values smaller than L (from -L to +L), and L is a variational parameter.
Use the variational method and the proposed form of a trial function to find the following:
(a) the best L value
(b) the best energy for the lowest vibrational state (zero point vibration)
