Question

The following data was collected during the calorimetric run. Graph the data and answer the questions below. (Enter your answers to three significant figures.) Table 1: Time and Temperature Data What is the initial temperature based on the calorimetric run? What is the final temperature based on the calorimetric run? If the total mass of the solution v/as 34.2 g and the heat capacity of the solution is the same as water (4.1801 J/g-degreeC), what is the value of q for the run? What is the value of q for the reaction?

Explanation / Answer

The final temperature is 15.2 °C according to the data in the chart.

Now for the value of q:

q = m*cp*(Tf-Ti)
q = 34.2 * 4.1801 * (23.9-15.2)
q = 1243.75 J

Now the value of q for the reaction I think is the same as the run.

Hope this helps
