Draw the Borne Haber cycle for KBr

2. Relevant equations

3. The attempt at a solution

so the energy required to make the K into gas is +89kJ/mol

and it takes +420kJ/mol to take 1 electron from K

it takes +112kJ/mol to make Br a gas

it takes -342kJ/mol to give the Br an electron

and i was given -392 delta H subscrpit F superscript theta = -392kJ/mol (what does this mean?)

how do i calculate the lattice enthalpy?

Using Hess's law it should be the sum

So is it

89+420+112-342-392???
