Question

Typical electronic energy gaps in molecules are about 1.0 ev, in terms of temperature, the gap is closest to-

Answer 1

Answer:

If you convert eV ( electron Volt ) into K (Kelvin) . Basically you are converting Energy (Joule) into Temperature (Kelvin)

1eV = 1.6 * 10 -19 J

For Converting it into K , We need Boltzman Constant as per the equation Suggested :

Kelvin (K) = ( 1eV / kB ) [Where , kB = 1.38 *10 -23 J/K ]

Kelvin (K) = ( 1.6 * 10 -19 J / 1.38 *10 -23 J/K ) = 11604 K equivalent to 10^4 K

So, It is Equivalent to Option (C)
