Question

The ionization energy per mole of hydrogen atoms in terms of Rydberg constant ($R_H$) is given by the expression :

• A. $R_H$hc
• B. $R_H$c
• C. 2 $R_H$ hc
• D. $R_H$ $N_A$ hc

Answer 1

The correct option is B $R_H$c

$\begin{array}{c}\frac{hc}{\lambda }=13.6\frac{z^2}{n^2}\\ \Rightarrow \frac{1}{\lambda }=R\left(\frac{z^2}{n^2}\right)\\ \Rightarrow \frac{hc}{\lambda }=R_{H}c\\ Hence,\\ optionBiscorrectanswer.\end{array}$
