Question 1

The heat combustion of acetylene, C2H2(g), at 25°C is –1299 kJ/mol. At this temperature, ΔHf° values for CO2(g) and H2O(l) are –393 and –286 kJ/mol, respectively. Calculate ΔHf° for acetylene.

◦ 2376 kJ/mol
◦ 625 kJ/mol
◦ 227 kJ/mol
◦ –625 kJ/mol
◦ –227 kJ/mol

Question 2

The heat of combustion of benzene, C6H6, is –41.74 kJ/g. Combustion of 3.21 g of benzene causes a temperature rise of 3.95°C in a certain bomb calorimeter. What is the heat capacity of this bomb calorimeter?

◦ 529 kJ/°C
◦ 33.9 kJ/°C
◦ 0.304 kJ/°C
◦ 5.65 kJ/°C
◦ 134 kJ/°C
