QAIPMT-2009-Ch-2108: NEET 2009 Chemistry - Class 11 AIPMT-2009-Ch-2108 Solution: The energy absorbed by each molecule (\(A_2\)) of a substance…

The energy absorbed by each molecule (A2A_2) of a substance is 4.4×10−194.4\times10^{-19} J and bond energy per molecule is 4.0×10−194.0\times10^{-19} J. The kinetic energy of the molecule per atom will be

Multiple Choice Options

  • A 2.2×10−192.2\times10^{-19} J
  • B 2.0×10−192.0\times10^{-19} J
  • C 4.0×10−204.0\times10^{-20} J
  • D 2.0×10−202.0\times10^{-20} J

Step-by-Step Verified Solution

Energy absorbed by each molecule = Bond energy per molecule + Kinetic energy per molecule _ 4.4 _ 10 �19 J = 4.0 _ 10 �19 J + Kinetic energy per molecule _ 0.4 _ 10 �19 = Kinetic energy per molecule Kinetic energy per atom = Kinetic energy per molecule 2 = 0.4 _ 10 �19 2 = 0.2 _ 10 �19 J = 2 _ 10 �20 J
