In the conversion of limestone to lime, CaCO3(s) ⇌ CaO(s) + CO2(g), t...
To determine the temperature above which the conversion of limestone to lime will be spontaneous, we can use the Gibbs free energy equation:
ΔG = ΔH - TΔS
where ΔG is the change in Gibbs free energy, ΔH is the change in enthalpy, T is the temperature in Kelvin, and ΔS is the change in entropy.
Since we want to find the temperature above which the conversion is spontaneous, we need to find the temperature at which ΔG is negative.
Given information:
ΔH0 = 179.1 kJ mol-1 (convert to J mol-1)
ΔS0 = 160.2 J/K
T = 298 K
Converting ΔH0 to J mol-1:
ΔH0 = 179.1 kJ mol-1 = 179.1 × 10^3 J mol-1
Calculating ΔG at 298 K:
ΔG = ΔH - TΔS
ΔG = (179.1 × 10^3 J mol-1) - (298 K × 160.2 J/K)
ΔG = 179.1 × 10^3 J mol-1 - 47.7 × 10^3 J mol-1
ΔG = 131.4 × 10^3 J mol-1
Since ΔG is positive at 298 K, the conversion of limestone to lime is not spontaneous at this temperature.
To find the temperature at which ΔG becomes negative, we can set ΔG equal to zero and solve for T:
0 = ΔH - TΔS
TΔS = ΔH
T = ΔH/ΔS
Calculating the temperature using the given values:
T = (179.1 × 10^3 J mol-1)/(160.2 J/K)
T = 1118 K
Therefore, the temperature above which the conversion of limestone to lime will be spontaneous is 1118 K. The correct answer is option D.
ΔG = ΔH - TΔS
where ΔG is the change in Gibbs free energy, ΔH is the change in enthalpy, T is the temperature in Kelvin, and ΔS is the change in entropy.
Since we want to find the temperature above which the conversion is spontaneous, we need to find the temperature at which ΔG is negative.
Given information:
ΔH0 = 179.1 kJ mol-1 (convert to J mol-1)
ΔS0 = 160.2 J/K
T = 298 K
Converting ΔH0 to J mol-1:
ΔH0 = 179.1 kJ mol-1 = 179.1 × 10^3 J mol-1
Calculating ΔG at 298 K:
ΔG = ΔH - TΔS
ΔG = (179.1 × 10^3 J mol-1) - (298 K × 160.2 J/K)
ΔG = 179.1 × 10^3 J mol-1 - 47.7 × 10^3 J mol-1
ΔG = 131.4 × 10^3 J mol-1
Since ΔG is positive at 298 K, the conversion of limestone to lime is not spontaneous at this temperature.
To find the temperature at which ΔG becomes negative, we can set ΔG equal to zero and solve for T:
0 = ΔH - TΔS
TΔS = ΔH
T = ΔH/ΔS
Calculating the temperature using the given values:
T = (179.1 × 10^3 J mol-1)/(160.2 J/K)
T = 1118 K
Therefore, the temperature above which the conversion of limestone to lime will be spontaneous is 1118 K. The correct answer is option D.
