Question

Using the thermodynamic data below calculate the ΔS°_rxn for the following reaction and justify the change in entropy.

CO(g) + NH₃(g) → HCN(g) + H₂O(g)

Table showing standard entropy values for CO, NH3, HCN, and H2O in J/mol·K.

Accepted Answer

ΔS°_rxn = +0.1 J/mol; The change in entropy is very small because the moles of gas in the reaction are the same.

Answer

ΔS°_rxn = +6.1 J/mol; The change in entropy is very small because the moles of gas in the reaction are the same.

Answer

ΔS°_rxn = –0.1 J/mol; The change in entropy is very small because the size and shape of the species in the reaction are the same.

Answer

ΔS°_rxn = –6.1 J/mol; The change in entropy is very small because the size and shape of the species in the reaction are the same.
