A student wishes to calculate the gas phase Gibbs free energy change for the following reaction (at 298 K and 1 atm): CH3CH2CH2COOH(g) --> CH3CH2CH2COO-(g) + H*(g) To do so, the student performed a HF/6-31G(d) geometry optimisation and frequency calculation for each species but the result differs significantly from the experimental value. There are several options available to the student to improve the accuracy of this prediction. Which of the following is least likely to remedy...
