In an acid catalysed hydrolysis reaction of ethyl ethanoate, the concentration of the ester changes from $1.50 \mathrm{mol} {\mathrm{dm}}^{-3}$ to $0.35 \mathrm{mol} {\mathrm{dm}}^{-3}$ in $3.5 \min$, at a given temperature, ${\mathrm{T}}_1$. Which of the following statements are correct?

I. The average rate of the reaction is $0.33 \mathrm{mol} {\mathrm{dm}}^{-3} {\min }^{-1}$.

II. If the reaction is carried out at a higher temperature, ${\mathrm{T}}_2$, the reaction rate will be greater.

III. The products of the reaction will be ethanoic acid and ethanol.
