Question

A molecule X2 dissociates into atoms after absorbing light of 1320 Å. If one quantum of radiation is absorbed by each molecule, then the kinetic energy of X atom is
[Given, bond energy of X2 is 500 kJ/mol]
[h = 6.6 × 10–34 Js]
1320 Å का प्रकाश अवशोषित करने के बाद एक अणु X2 अपने परमाणुओं में वियोजित हो जाता है। यदि प्रत्येक अणु द्वारा विकिरण का एक क्वाण्टम अवशोषित होता है, तो X परमाणु की गतिज ऊर्जा है
[दिया गया है, X2 की बन्ध ऊर्जा 500 kJ/mol है]
[h = 6.6 × 10–34 Js]
