Doubling the concentration of base will double the rate of both the reactions.

Changing the concentration of base will have no effect on reaction ($\displaystyle 2$).

Changing the concentration of base will have no effect on reaction ($\displaystyle 1$).

Changing the base from $\displaystyle \mathrm{OH}^{\ominus}$ to $\displaystyle { }^{\ominus}$ OR will have no effect on reaction ($\displaystyle 2$).
