The electron affinity of bromine is 3....

The electron affinity of bromine is 3.36 eV . How much energy in kcal is released when 8g of bromine is completely converted to `Br^(-)` ions in the gaseous state ? (1eV =23. 06 kcal `mol^(-1)`)

Text Solution

Verified by Experts

The correct Answer is:
`7.75`
No. of moles of Br = 8 / 80 = 1.0 Required energy `= 0.1 xx 3.36 xx 23.06= 7.748` k cal
