As per your syllabus, what is the energy of one mole of photons of radiation of frequency 5 × 10¹⁴ Hz?
A~6.626 × 10⁻³⁴ kJ mol⁻¹
B~6.022 × 10²³ kJ mol⁻¹
C~199.5 kJ mol⁻¹
D~3.31 × 10⁻¹⁹ kJ mol⁻¹
Answer & Solution
Correct answer: C. ~199.5 kJ mol⁻¹
As per your syllabus, E_photon = hν = 3.313 × 10⁻¹⁹ J; per mole = × N_A = 199.5 kJ mol⁻¹.
