# Problem: Calculate K at 298 K for the following reaction:(b) SrSO4(s) ⇌ Sr2+(aq) + SO42−(aq)

###### FREE Expert Solution

SrSO4(s) ⇌ Sr2+(aq) + SO42−(aq)

Recall that ΔG˚rxn and K are related to each other:

$\overline{){\mathbf{\Delta G}}{{\mathbf{°}}}_{{\mathbf{rxn}}}{\mathbf{=}}{\mathbf{-}}{\mathbf{RTlnK}}}$

We can use the following equation to solve for ΔG˚rxn:

Solving for ΔG˚rxn:

ΔG˚rxn = 36.90 kJ/mol

We also need to convert ΔG˚rxn from kJ to J:
