Solution: A 0.500-L sample of 0.400 M Na2CO3 (aq) is added to 0.500 L of 0.400 M Ba(NO 3)2 (aq) in a calorimeter with a total heat capacity equal to 656 J•K –1 at a constant pressure of one bar. The temperature

Problem

A 0.500-L sample of 0.400 M Na2CO3 (aq) is added to 0.500 L of 0.400 M Ba(NO 3)2 (aq) in a calorimeter with a total heat capacity equal to 656 J•K –1 at a constant pressure of one bar. The temperature change is +1.25 K. Use these data to calculate the value of ΔH°rxn for the equation:
