Question 1

Which of the following processes is endothermic?
◦ an atom emits a photon
◦ the electron affinity of a fluorine atom
◦ the condensation of water
◦ an atom absorbs a photon
◦ None of the above processes is endothermic.

Question 2

Using the following equation for the combustion of octane, calculate the heat of reaction for 100.0 g of octane. The molar mass of octane is 114.33 g mol-1.

2C8H18 + 25O2 → 16CO2 + 18H2ODrH° = -11018 kJ

◦ 4.82 kJ
◦ 1.26 × 104 kJ
◦ 4.82 × 103 kJ
◦ 9.64 × 103 kJ
