🤓 Based on our data, we think this question is relevant for Professor Bindell's class at UCF.
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.
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.
