The electron gain enthalpy of chlorine is `–349 kJ mol^(–1)` . How much energy in kJ is released when 3.55 g of chlorine is converted completely into `Cl^(–1)` ion in the gaseous state?

Text Solution

Verified by Experts

For 35.5 gm Cl , EGE = - 349 kJ For 1 gm Cl , EGE = ` - (349)/(35.5)`
For 3.55 gm Cl , EGE ` = (-349)/(35.5) xx 3.55 = -34.9 kJ `
