Question

The activity coefficient (y) of a neutral molecule is typically approximated as 1.00; however, a more accurate determination can
be made by using the equation,
log (y) = ku
where k≈ 0.2 for organic molecules and is the ionic strength. Using the activity coefficients for H, A, and HA, calculate
the value of the given concentration quotient for acetic acid (HA = CH₂CO,H). You will need to look up the activity
coefficients for H and A in a table.
