Final answer:
The total heat change (qp) for a reaction carried in a calorimeter at constant pressure is equal to the change in enthalpy (ΔHrxn) of the reaction.
Step-by-step explanation:
The total heat change (qp) for a reaction carried in a calorimeter at constant pressure is equal to the change in enthalpy (ΔHrxn) of the reaction.
The heat released or absorbed at constant pressure is numerically equal to the change in enthalpy of the reaction. This relationship can be represented by the equation: ΔHrxn = qp.
