Can we assume that enthalpy of reaction(change in enthalpy) is the same as heat transferred(q)?

If the reaction is conducted at constant pressure, then heat transferred (qp) will be equal to the enthalpy of the reaction (ΔH).
Enthalpy is specifically the heat released or absorbed at constant pressure, so make sure that pressure is constant (reaction is not in a bomb calorimeter) before assuming that the heat transfer is enthalpy.
