1. Suppose you burn 10.00g octane (C8H18) in a (very very very large) container with a moveable piston. Assuming a temperature of 500K and expansion against 1.00atm of pressure, how much work, in Joules, can be done by the system if the octane is completely converted to carbon dioxide and water vapor? What will the enthalpy change be for the process?

2. Calculate the root-mean-square speed of the carbon dioxide molecules in the question above.
