Question

Suppose a given chemical mixture has the potential to produce so that the sum of the bond strengths is larger than those of the reactants but that the number of moles of reactant gases arc decreased. Can you tell if the reaction will occur? For each, at T, P constant give the sign of the Gibbs energy: a. Ice melts at 0 degree C and 1 bar? b. Water boils at 100 degree C and 1 bar? c. The vapor pressure of water at 20 degree C is 17.36 torr? d. CaCO_3(s) rightarrow CO_2(g) + CaO(s)? The standard heats of formation and entropies of diamond and graphite at 25 degree C are given in the table. For the conversion of diamond to graphite at 25 degree C, calculate What can you say about the slogan "a diamond is forever"?

Explanation / Answer

First if the bond strength is larger in products, that menas that the compound will no suffer any descomposition. so the reaction will occur but it´ll need some energy for the formation of the bonds.
