Calculating Entropy Change?

Answer

To calculate change in entropy, determine the standard entropies of all products and reactants using the entropy table. Given the equation 2H2O + CO2 ' CH4 + 2O2, the entropies would be 188.7 for H2O, 213.6 for CO2, 186 for CH4, and 205 for O2. Total the entropies of all of the products and of all of the reactants. Subtract the entropies of the reactants from the entropies of the products
