Question

Energy absorbed by 1 mole substance in
photochemical reactions is called -​

Answer 1

answer : one Enstien

explanation : Albert Enstien was developed the concept of photoelectric effect. due to his honour, energy of one mole of photon in photochemical reactions is known as one Enstien

according to Plank's quantum theory,

energy of one photon, E = hv

and energy of one mole of photon = 6.023 × 10²³ × E

[ as you know, one of photons means 6.023 × 10²³ photons . that means, energy of one mole of photons = energy of 6.023 × 10²³ photons ]

= 6.023 × 10²³ × hv [ this amount of energy is known as one Enstien ].

Answer 2

Answer:

Energy absorbed by 1 mole substance in   photochemical reactions is called 1 Enstien.

Energy of one mole of photon in photochemical reactions is known as one Enstien.

According to Plank's quantum theory,

energy of one photon, E = hv

and energy of one mole of photon = 6.023 × 10²³ × E

one of photons means 6.023 × 10²³ photons . that means, energy of one mole of photons = energy of 6.023 × 10²³ photons

= 6.023 × 10²³ × hv [ This is known as Enstien ].
