Unformatted text preview: an exothermic reaction takes place. e) In an adiabatic bomb calorimeter experiment, we adjust the amount of reactants so the measured temperature change is large enough that it can be measured but small enough that isothermal conditions can be assumed when calculating standard reaction enthalpies. f) The standard formation enthalpy of iodine is only equal to zero when iodine is in the pure solid molecular state (I2(s)) under standard pressure. Question 7: (10 points) Using the thermodynamic data reported at 298.15K (shown below), determine the standard reaction enthalpy at 378.15K for the reaction: CH4(g) + 2 Cl2(g) à༎ CCl4(l) + 2 H2(g) Substance CH4(g) Cl2(g) CCl4(l) H2(g) o ΔfH 298.15 K (kJ/mol) - 74.8 - - - - 128.4 -...
