The Lennard-Jones parameters for the interactions between benzene, C₆H₆, molecules are $\varepsilon$ = 454 kJ mol^-1 and r₀ = 527 pm. Calculate the separation that corresponds to the minimum in the Lennard-Jones potential.

Question

Quizplus · Accepted Answer

The separation that corresponds to the minimum in the Lennard-Jones potential is given by $r_{min} = 2^{1/6} \times \sigma$, where $\sigma$ is the distance at which the potential energy is zero. Given $\sigma = 527$ pm, $r_{min} = 2^{1/6} \times 527$ pm ≈ 592 pm.
