Question 3: thermodynamic (20 marks) 3.1. a 1.435g of naphthalene (ch) was burned in constant volume bomb calorimeter. consequently temperature of the water rose from 20.17â°c to 25.84â°c. if the mass of water surrounding the calorimeter was exactly 2.0 x 10kg and the heat capacity of the bob calorimeter was 1.80 kj/â°c, calculate the molar heat of reaction (combustion) in kj of naphthalene. (10) 3.2 propane (ch) has a normal boiling point of -42.0â°c and a heat of vaporization (hvapo) of 19.04kj/mol. what is the vapor pressure of propane at 25.0â°c? (5) 3.3 one of the methods for synthesizing methanol (ch30h) involves reacting co with h2. the equilibrium is co2h2 () ch2oh(a). at 427â°c a mixture of co, h, and ch. oh having the following partial pressures; pco= 2.0 x 10'atm, ph2= 1.0x10â° atm and pch. oh = 1.0 x 10â°. for this reaction grook = 13.5 kj. determine whether the system is at equilibrium?
