Q109 · CSIR NET Chemistry, December 2011
Paper: CSIR NET December 2011 · Subject: Physical Chemistry · Chapter: Quantum Chemistry · Topic: Particle In A Box · Marks: 2 · Difficulty: Medium
A particle is constrained in a one dimensional box of length 2a with potential $V(x) = \infty$; $x < -a$, $x > a$ and $V(x) = 0$; $-a \leq x \leq a$. Energy difference between levels $n = 3$ and $n = 2$ is
(a)$\frac{5h^2}{8ma^2}$
(b)$\frac{9h^2}{8ma^2}$
(c)$\frac{9h^2}{32ma^2}$
(d)$\frac{5h^2}{32ma^2}$
