`Cl_(2)` की बंध वियोजन ऊर्जा 240 kJ/mol है। फोटॉन की सबसे लंबी तरंग दैर्ध्य, जो इस बंध को तोड़ सकती है, होगी
`[N_(A) =6xx10^(23), h=6.6 xx10^(-34) J//s]`

A

`4.95 xx 10^(-7)m`

B

`9.9xx10^(-7)m`

C

`4.95 xx 10^(-6)m`

D

`9.9 xx 10^(-6)m`

Text Solution

Verified by Experts

The correct Answer is:
A
`E=N_(A) xx (hC)/(lambda)`
`240xx10^(3) = (6xx10^(23) xx 6.6 xx10^(-34)xx3 xx 10^(8))/(lambda)`
`lambda =4.95 xx 10^(-7)m`

Bond dissociation on energy of Cl_(2) is 240 kJ/mol. The longest wavelength of photon that can break this bond would be [N_(A)=6xx10^(23), h=6.6xx10^(-34)J/s]

The energy of a photon of wavelength 4000 Å is (use h=6.66xx10^(-34) J-s)

In a measurement of quantum efficiency of photosynthesis in green plants, it was found that 10 quanta of red light of wavelength 6850 Å were needed to release one molecule of O_(2) . The average energy storage in this process for 1 mol O_(2) evolved is 112 Kcal. What is the energy conversion efficieny in this experiment? Given: 1 cal =4.18 J, N_(A)=6xx10^(23),h=6.63xx10^(-34) J.s
