1. You have a 134.0g sample of water at -30 oC and you heat it until you have gaseous water at 140 oC. Calculate the energy required for this process.
2. N2 and O2 make up the majority of the Earth's atmosphere with partial pressures of 0.78 and 0.21 atm, respectively. These two gases are extremely stable at normal atmospheric temperatures. Inside of a lightning bolt, however, temperatures are hot enough that these two species react to form NO. You can use the following assumptions: the temperature is 2200 oC inside the lightning bolt, the bolt lasts long enough for all three species to reach equilibrium at that temperature, and the pressure of NO is 0.001 atm at equilibrium. Calculate the standard free energy change ΔGo for these conditions. (Note- this calculation will have some error in it because the gases are not in their standard states but we are calculating standard free energy. The point here is to see how different chemistry topics interact with each other (e.g. equilibrium and free energy). It is also a chance for you to practice using the equations and learn how to solve more challenging problems)
