Delta H at constant pressure

Why is deltaH equal to 0 at constant pressure?

Delta H is not necessarily equal to 0 at constant pressure. At constant pressure delta H is equal to q. Therefore if q were equal to 0 at constant pressure, then delta H would also be 0

At constant pressure delta H = q, which means q would have to be 0.
q is 0 when it is an adiabatic reaction.
