# Problem: Consider the reaction HCl (g) + NH3 (g) → NH4Cl (s) Using the Standard thermodynamic data, calculate the equilibrium constant for this reaction at 298.15 K. ANSWER: ____________

###### FREE Expert Solution

We’re being asked to determine the equilibrium constant (K) at 298.15 K for the given reaction:

HCl(g) + NH3(g)  NH4Cl(s)

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:
