Chapter 20, Problem 23PS

Interpretation Introduction

Interpretation:

It should be confirmed that oxidation of $1.0L$ methanol to form$C{O}_{2\left(g\right)}$and$H_2{O}_{\left(l\right)}$in a fuel cell will provide at least $5.0kWh$of energy.

Concept Introduction:

• Standard enthalpy of reaction ${\Delta }_r{H}^0$ is the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, when all reactants and products are in their standard states. 
• Enthalpy of formation is the heat released or absorbed in a chemical reaction at constant temperature when simple substances combine into a more complex substance.
• $\text{1}\text{kWh}\text{=}\text{3600}\text{kJ}$
