Questiоn 2 A student dоes sоme experiments to find the heаt energy releаsed when nаtural gas burns. She uses this apparatus. See addendum under question 2. Figure 2. a The diagram shows the thermometer readings in one of her experiments. See addendum under Question 2. Figure 2a. Use these readings to complete the table, entering all values to the nearest 0.1 °C (3) Temperature of the water at the start in oC Temperature of the water at the end in oC Temperature change in oC b The student repeats the experiment three times. The table shows her results. Experiment Volume of gas burned in cm3 Temperature rise of water in oC 1 1450 34.8 2 1875 41.2 3 1620 37.7 bi Calculate the amount, in moles, at room temperature and pressure, of methane burned in experiment 1. (2) Assume that natural gas contains only methane. (The volume of 1 mol of a gas at room temperature and pressure is 24 000 cm3) amount = ........................................................... mol bii The quantity of heat energy released in experiment 1 is 29 200 J. (2) Calculate the molar enthalpy change, in kJ/mol, for the combustion of methane. molar enthalpy change = ........................................................... kJ/mol biii The temperature rise in experiment 2 is 41.2 °C. (2) Calculate the heat energy change in experiment 2 using the expression heat energy change = volume of water × 4.2 × temperature change (in J) (in cm3) (in °C) heat energy change = ........................................................... J biv The student uses the results from experiment 3 to calculate the molar enthalpy change, in kJ/mol, for the combustion of methane. (1) She compares her value with the value in a data book.
