bond length - 2024 PLAYTIME

Question

Single-point energies of a diatomic molecule scanned at different values for this quantity can match those on a Morse potential diagram, whose x-axis is this quantity. For 10 points each:

[10e] Name this quantity, which is about 1.1 angstroms for a carbon–hydrogen bond.

ANSWER: bond length

[10m] The length of a linear extended conjugated system can be calculated by using UV/vis spectroscopy and applying the one-dimensional form of this model. The potential of this model is zero within a certain region, but infinite everywhere else.

ANSWER: particle in a box model [or PIAB; or infinite square well or infinite potential well; prompt on quantum well or potential well]

[10h] Bond lengths of simpler molecules can be approximated indirectly via their surface area by using a Wilhelmy plate and this equation, which features the partial derivative of lowercase gamma with respect to log c.

ANSWER: Gibbs isotherm equation [accept Gibbs adsorption isotherm equation]
