Module 1—Thinking Energy

Reflect on the Big Picture

 

Evaluating Two Liquid Fuels

 

Liquid fuels might be very useful in the operation of your ecotour. Two popular choices are methanol and ethanol.

 

RBP 1. Analyze the information below. Explain how your understanding of communicating enthalpy changes could help you identify which of these fuels is preferred with respect to its energy of combustion.

 

Fuel

Combustion Reaction Equation

ΔcHº

Methanol

2 CH3OH(l) + 3 O2(g) → 2 CO2(g) + 4 H2O(g)

-1275.8 kJ

Ethanol

 C2H5OH(l) + 3 O2(g) → 2 CO2(g) + 3 H2O(g)

-1234.8 kJ

 

Save a copy of your response in your ecotour planning sub-folder. This is the fifth of six assignments that you can submit as part of your Module 1 Assessment. For more information, refer to the Module 1 Assessment.
