A 238 G Sample of Phenol (C₆H₆O, Molar Mass = 94

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 Δ_rU for the combustion of phenol.

A) -8.19 × 10³ kJ mol^-1
B) -5.81 × 10³ kJ mol^-1
C) 4.87 × 10³ kJ mol^-1
D) -3.05 × 10³ kJ mol^-1
E) 2.41 × 10³ kJ mol^-1
