Question

# In Born-Haber cycle, the sum of the enthalpy changes around a cycle is Constant Zero Positive integer Negative integer

Solution

## The correct option is B Zero The Born-Haber cycle, is based on Hess Law or Law of constant heat summation which states that the standard enthalpy of reaction is the sum of algebraic sum of the standard enthalpies of reactions into which the overall reaction may be splitted. So the change in enthalpy around a cycle is zero.
