Homework SourseThe reaction of 0130 moles of a metal with an acidic aqueous
The reaction of 0.130 moles of a metal with an acidic aqueous solution in a calibrated calorimeter causes the temperature to increase by 51.5
Solution
total heat evolved = (74*3.85 + 5) ( change in temp) = (74*3.85 + 5) ( 51.5) = 4088.32J = 4.088 KJ
=> ?Hreaction in kJ/mol metal = 4.088/0.13 = 31.45 KJ/mol
