Question

Find out the value of (P) in the following cycle:

Given `DeltaH_(1) =- 400 kJ, I.E. = + 50 kJ, D = + 50 kJ, DeltaH_(eg) = - 30 kJ` lattice energy `- - 100 kJ`
A. `-400 kJ`
B. `-300 kJ`
C. `-370 kJ`
D. `-310 kJ`

Answer 1

Correct Answer - C
`DeltaH_(1) = D +IE +DeltaH_(eg) = P +DeltaH_(L.E)`
