For a photochemical reaction

\mathrm{A} \rightarrow \mathrm{B},\,\,1 \times 10^{-5}

moles of '

B

' were formed on absorption of

6.626 \times 10^7

erg at

360 \mathrm{~nm}

. The quantum efficiency (molecules of '

B

' formed per photon) is

\left(N_{\mathrm{A}}=6 \times 10^{23}\right)

View answer and explanation

Correct option: C

0.5

Option C (0.5) is correct because the quantum efficiency is calculated by dividing the moles of B formed by the moles of photons absorbed.
