If for heterogeneous equilibrium, `CaCO_3(s)hArr CaO(s)+CO_2(g), K_(eq)=1` at `1 atm` pressure, the corresponding temperature is given byA. `T=(DeltaG^(Θ))/(DeltaH^(Θ))`B. `T=(DeltaG^(Θ))/(R)`C. `T=(DeltaS^(Θ))/(DeltaH)`D. `T=(DeltaH^(Θ))/(DeltaS^(Θ))` |

Answer» Correct Answer - D According to thermodynamics `DeltaG^(Θ)=DeltaH^(Θ)-TDeltaS^(Θ)` At equilibrium, `DeltaG^(Θ)=0`. Thus, `0=DeltaH^(Θ)-TDeltaS^(Θ)` `DeltaH^(Θ)=TDeltaS^(Θ)` `T=DeltaH^(Θ)//DeltaS^(Θ)` |
