27 of 42 (> Constants | Periodic Table A calorimeter is an insulated device in which a chemical reaction is contained. By measuring the temperature change, AT, we can calculate the heat released or absorbed during the reaction using the following equation: Consider the reaction C12 H22O11 (s) + 1202(g)-12CO2(g) + 11H2O(1) in which 10.0 g of sucrose, C12 H22011, was bumed in a bomb calorimeter with a heat capacity of 7.50 kJ/C. The temperature increase inside the calorimeter was found to be 22.0°C. Calculate the change in internal energy, AE, for this reaction per mole of sucrose. q= specific heat x mass x AT Or, if the calorimeter has a predetermined heat capacity, C, the equation becomes Express the change in internal energy in kilojoules per mole to three significant figures. 9=C x AT • View Available Hint(s) At constant pressure, the enthalpy change for the reaction, AH, is equal to the heat, gp, that is, V ΑΣφ ?

Consider a piston (or box) pressurized with air. Suppose you compress the piston so that the final volume is half the starting volume but the temperature remains the same. For a reversible process, i) would the work done on the system be the same or change whether you modeled the gas ideal or real? ii) For an irreversible process, would the work done on the system be the same or change whether you modeled the gas as ideal or real assumng that you applied the same external force for compression?
