A level chemistry - energetics enthalpy diagrams

Do we need to know this type of diagram as I haven't been taught this way I don't think. I was taught to use the cycle where the arrows are curved etc

if this is a normal born-haber cycle diagram you need to know this as previous questions have come up asking students to draw a born-haber diagram

Sometimes they are interchangeable but yes you must know how to draw a Born-Haber cycle!

If you're doing AS then no, don't need it. Just Hess cycles :smile:
