Answer
### The reactants are favored.
Explanation
## Step1: Identify the Products### The reaction between acetic acid (
) and ammonia (
) forms ammonium acetate (
). The chemical equation is:
## Step2: Calculate the Equilibrium Constants### The
value for acetic acid (
) is
. The
value for the conjugate acid formed in the reaction, which is ammonium ion (
), is
.## Step3: Determine Reaction Direction### To determine which side is favored, compare the
values. The larger
value indicates a stronger acid, while the smaller
value indicates a weaker acid.
Since
of acetic acid (
) is greater than
of the conjugate acid (
), the reaction favors the reactants.
