1.) The value of
S° for the oxidation of carbon to carbon dioxide,
is __________ J/K
mol. The combustion of carbon, as in charcoal briquettes, in the
presence of abundant oxygen produces carbon dioxide.
2.)The value of
S° for the reaction
is __________ J/K.
3.)The value of
S° for the decomposition of gaseous sulfur dioxide to solid
elemental sulfur and gaseous oxygen,
is __________ J/K
mol.
