Question: I.E. of one H atom is $ 2.18\times {{10}^{-18}}J $ . The I.E. of H atom is $ kJmol{{e}^{-1}} $ is -
Options:
A) $ 1505,kJ,mo{{l}^{-1}} $
B) $ 1310,kJ,mo{{l}^{-1}} $
C) $ 1608,kJ,mo{{l}^{-1}} $
D) None
Show Answer
Answer:
Correct Answer: B
Solution:
[b] $ I\text{.E}\text{.=}\frac{2\text{.18 }\times\text{ 1}{{0}^{\text{-18}}}J}{1atom}\times\frac{6\text{.02 }\times\text{ 1}{{0}^{23}}atom}{mole} $
$ \text{=1}\text{.31 }\times\text{ 1}{{0}^{6}}\text{J mol}{{e}^{-1}}\text{=1310 KJ mol}{{e}^{\text{-1}}} $
