Question 1

A 4.98 g sample of aniline (C6H5NH2, molar mass = 93.13 g mol-1) was combusted in a bomb calorimeter with a heat capacity of 4.25 kJ °C-1. If the temperature rose from 29.5 °C to 69.8 °C, determine the value of DrU for the combustion of aniline.
◦ +1.71 × 103 kJ mol-1
◦ -3.20 × 103 kJ mol-1
◦ -1.71 × 103 kJ mol-1
◦ +7.81 × 103 kJ mol-1
◦ -7.81 × 103 kJ mol-1

Question 2

A 2.38 g sample of phenol (C6H6O, molar mass = 94.11 g mol-1) was combusted in a bomb calorimeter with a heat capacity of 6.65 kJ °C-1. If the temperature increased from 23.8 °C to 35.4 °C, determine DrU for the combustion of phenol.
◦ -8.19 × 103 kJ mol-1
◦ -5.81 × 103 kJ mol-1
◦ 4.87 × 103 kJ mol-1
◦ 2.41 × 103 kJ mol-1
◦ -3.05 × 103 kJ mol-1
