Which statement is true? O a. A state function is one whose value for a system depends on the method of preparation of the reactants and products. O b. A state function is one whose value for the system is determined by only the pressure of the system, and not on the temperature of the system. O c. A state function is one whose value for a system is determined by the temperature of the system, and not on the composition of the system. O d. A state function is one whose value for a system is determined by the composition of the system, the volume, the temperature, and the pressure. O e. A state function is one whose value for a system is determined by the difference in temperature of the system, and not on the pressure of the system. Clear my choice Next page
* t dhe calorimetry experiment was used to measure the heat of reaction for an endothermic process, what would have been different about the observed change in temperature? 2. When calculating the heat of reaction why did we have to add in C AT? calorimeter 3. Why were we able to assume that the C solution = C water 4. The data collected today may have shown a decrease in temperature after several minutes of constant temperature. What does the eventual decrease in temperature tell us about the calorimeter? 5. In a calorimetry experiment similar to the one performed today, a student used 50.0 mL of 1.0 M NaOH and 50.0 mL of 1.0 M HCl each initially at 22.5 °C. The maximum temperature observed after mixing was 28.0 °C. What is the heat of reaction in units of kJ? Show all work. 6.
