We’re being asked to determine the equilibrium constant (K) at 298 K for the given reaction:
2 SO2(g) + O2(g) ⇌ 2 SO3(g)
Recall that ΔG˚rxn and K are related to each other:
We’re given the ΔH˚f and S˚ of each reactant and product:
S˚ (J/mol • K)
We can use the following equation to solve for ΔG˚rxn:
For this problem, we need to do the following steps:
Step 1: Calculate ΔH˚rxn.
Step 2: Calculate ΔS˚rxn.
Step 3: Use ΔH˚rxn and ΔS˚rxn to calculate for ΔG˚rxn.
Step 4: Calculate for K.
Given the thermodynamic data in the table below, calculate the equilibrium constant (at 298 K) for the reaction:
2SO2 (g) + O2(g) ⇌ 2SO3(g)
a) 2.37 x 1024
d) 3.92 x 1023
e) More information is needed.
