Question 1

Calculate the change in internal energy (ΔU) for a system that is absorbing 35.8 kJ of heat and is expanding from 8.00 to 24.0 L in volume at 1.00 bar. (Remember that 100 J = 1 L bar)
◦ -29.3 kJ
◦ +51.8 kJ
◦ -15.8 kJ
◦ +34.2 kJ
◦ -16.6 kJ

Question 2

A 6.55 g sample of aniline (C6H5NH2, molar mass = 93.13 g mol-1) was combusted in a bomb calorimeter. If the temperature rose by 32.9 °C, use the information below to determine the heat capacity of the calorimeter.

4C6H5NH2(l) + 35O2(g) → 24CO2(g) + 14H2O(g) + 4NO2(g)

DrU= -3.20 × 103 kJ mol-1

◦ 38.9 kJ °C-1
◦ 12.8 kJ °C-1
◦ 5.94 kJ °C-1
◦ 6.84 kJ °C-1
◦ 97.3 kJ °C-1
