Redox Reactions And Electrochemistry Ques 296
Question: The energy required to release 1 electron from $ H{e^{+}} $ is–. [Orissa JEE 2002]
Options:
A) + 54.4 eV
B) - 13.6 eV
C) + 27.2 eV
D) Cannot be predicted
Show Answer
Answer:
Correct Answer: B
Solution:
$ E=-\frac{13.6}{n^{2}}forH{e^{+}}n=1 $ $ E=-\frac{13.6}{1^{2}}=-13.6,eV $ .
