To calculate the free energy change of the reaction, we can use the equation:
ΔG = -RT ln(Kc)
Where:
ΔG = free energy change of the reaction (in Latm)
R = ideal gas constant (0.082 LatmK⁻¹mol⁻¹)
T = temperature in Kelvin (291K)
ln = natural logarithm
Kc = equilibrium constant (1.14)
First, let's convert the concentration from molarity to partial pressure. In an ideal gas, the partial pressure is directly proportional to the concentration. Since the concentration of both gases is 0.5 mol/L, we can assume that the partial pressure of each gas is also 0.5 atm.
Now, let's substitute the values into the equation:
ΔG = - (0.082 LatmK⁻¹mol⁻¹) * (291K) * ln(1.14)
Using a calculator, we can evaluate the natural logarithm of 1.14 and multiply it by -0.082 * 291 to find the free energy change of the reaction.
ΔG = - (0.082 LatmK⁻¹mol⁻¹) * (291K) * ln(1.14)
≈ -35.60 Latm
ΔG = -RT ln(Kc)
Where:
ΔG = free energy change of the reaction (in Latm)
R = ideal gas constant (0.082 LatmK⁻¹mol⁻¹)
