Chapter 8 Homework #117

Why is the net production 2/3 mole of gas? There are 2 moles of reactants and 4 moles of products so how is the change 2/3?

Since you have 3 moles of H2 however the question asks you for the energy for the production of 1 mol, you can divide all the coefficients by 3. So you would have 1/3CH4 + 1/3H2O -> 1/3CO2 + H2. This would give you a change in moles of 2/3.
