What is the difference between the classical and Keyenesian LRAS curve?

In the classical model, the economy operates at full capacity in the long-run. Even if wages and prices change, markets are efficient so they adjust to maintain full employment.

The Keynesian model suggests that the economy can have spare capacity, even in the long-run, as factors of production can be under-utilised.
