Palmitic acid (C16H32O2) is a major component of the oil from the fruit of oil palms (palm oil). The complete combustion of palmitic acid can be represented as: C16H32O2(s)+23O2(g)→16CO2(g)+16H2O(l) In a bomb calorimeter with a heat capacity of 10.66 kJ⋅∘C−1 0.7081 gg of palmitic acid (molar mass = 256.43 g⋅mol−1) was combusted. The temperature of the calorimeter was observed to rise by 2.580 ∘C. a. Determine the ΔrU for the combustion of palmitic acid. b. Determine the ΔrH (at 298 KK) for the combustion of palmitic acid.
